Dolby Vision Dolby's dynamic-metadata HDR format

What Dolby Vision actually is

Dolby Vision arrived in 2014 as the first commercially available consumer HDR format, predating HDR10's standardization. The mastering pipeline runs at 12 bits per channel with a 10,000-nit PQ EOTF ceiling, against HDR10's 10-bit per-channel pipeline and the more typical 1,000–4,000-nit mastering targets the wider HDR10 ecosystem uses.

The piece that does the actual work in living rooms is the metadata. Dolby Vision carries SMPTE ST 2086 static mastering-display colorimetry alongside SMPTE ST 2094-10 (Dolby format) dynamic metadata, which encodes per-scene or per-frame trim parameters — Lift, Gamma, Gain, Saturation, Chroma Weight — so the receiver tone-maps each shot individually instead of applying one static curve to the whole title. HDR10 tells the TV about the master once; Dolby Vision tells the TV about every scene.

Profiles 5, 7, 8.1, 8.4

The format ships in distribution profiles that consumers rarely see named on a box but that determine compatibility behavior.

Profile 5 is the single-layer 10-bit HEVC streaming profile encoded in Dolby's proprietary IPT-PQ-c2 (ICtCp-derived) color space; because it is not backward-compatible with HDR10, a decoder without a Dolby Vision license renders it as out-of-gamut/oversaturated. Netflix, Apple TV+, Disney+, and Max use Profile 5.

Profile 7 is the dual-layer profile used exclusively on UHD Blu-ray: a 10-bit HDR10-compatible HEVC base layer (BL) is paired with an enhancement layer (EL) that, combined by a Dolby Vision decoder, reconstructs a 12-bit image with the dynamic metadata applied. The EL exists in two variants — MEL (Minimum Enhancement Layer, metadata-only) and FEL (Full Enhancement Layer, which also carries residual picture data).

Profile 8.1 is a single-layer profile in which the underlying video stream is fully HDR10-compatible and Dolby Vision metadata is carried alongside it; a non-DV display falls back to standard HDR10, while a DV display uses the metadata for scene-by-scene tone mapping. The technical contrast with Profile 5 is base format and color space — HDR10 (BT.2020 / PQ / YCbCr) with DV metadata, versus non-backward-compatible IPT-PQ-c2.

Profile 8.4 is the HLG-compatible single-layer variant; the base layer is HLG (ITU-R BT.2100), so SDR and HDR receivers without DV support can still display the stream sensibly. Apple iPhones record video in this profile.

How it reaches the screen

On UHD Blu-ray, Dolby Vision is carried as Profile 7 dual-layer HEVC; players without DV support read only the base layer and play standard HDR10. Streaming services deliver Dolby Vision as single-layer HEVC, almost always Profile 5 — used by Netflix, Apple TV+, Disney+, and Max — or Profile 8.1 (HDR10-compatible base + DV metadata), which is more common on apps that need a clean HDR10 fallback on non-DV hardware.

Layered on top of the format itself is Dolby Vision IQ, an extension that uses the TV's built-in ambient-light sensor together with Dolby Vision metadata to dynamically adjust backlight level and the PQ tone curve so that creative intent holds across bright and dim viewing environments. IQ modulates luminance, not color, and is distinct from generic "eco" or auto-brightness modes because the adjustments are guided by the DV metadata's reference grading targets rather than a simple lux-to-backlight curve.

Dolby Vision 2 (2025–2026)

Dolby Vision 2 was announced by Dolby on 2 September 2025 and demonstrated on shipping hardware at CES 2026 in January 2026. It is built around a new image engine and a "Content Intelligence" layer, plus headline features Precision Black, Authentic Motion, and bi-directional tone mapping, and it ships in two tiers — Dolby Vision 2 (mainstream) and Dolby Vision 2 Max (flagship).

Authentic Motion is a creator-driven motion-handling tool that lets the colorist or director specify, on a shot-by-shot basis, how much judder reduction the renderer applies. It is metadata-guided rather than a fixed motion-smoothing preset, with the explicit goal of avoiding the soap-opera effect on 24p film, and it is exclusive to the Dolby Vision 2 Max tier.

Precision Black selectively lifts near-black detail to address the long-running complaint that HDR (and Dolby Vision in particular) looks "too dark" in typical living rooms while keeping deep blacks intact. It is part of the standard Dolby Vision 2 tier, not Max-exclusive.

Bi-directional tone mapping is the third headline feature: instead of only compressing a high-nit master down onto a less-capable display, the renderer can also expand toward a panel that exceeds the master's reference, so flagship 2026 sets with very high peak luminance and wider color volume can use their full headroom without diverging from the colorist's intent. Coverage from consumer outlets often labels this "MaxRGB" or "wider color volume," but Dolby's own announcement and the Display Daily summary use "bi-directional tone mapping" — these appear to be the same mechanism under different labels.

Dolby Vision 1's renderer is a one-way tone-mapper that takes the 12-bit / up-to-10,000-nit master plus per-scene metadata and compresses it onto the consumer display. Dolby Vision 2 replaces that with the new image engine, driven by Content Intelligence that combines the original DV trim metadata with display-capability data and (where available) ambient-light sensor input, then applies bi-directional tone mapping, Precision Black, and — on Max-tier hardware — Authentic Motion. DV2 still consumes existing Dolby Vision content streams, so it is backward-compatible at the file level; the upgrades live in the playback-side renderer and the new metadata Dolby is asking creators to ship.

Launch partners are Hisense, TCL, and TP Vision (Philips). Hisense's 2026 RGB MiniLED lineup (UX, UR9, UR8) ships with native Dolby Vision 2; TCL's 2026 X QD-Mini LED and C-series receive support via OTA firmware update; TP Vision's 2026 OLED811, OLED911, and flagship OLED951 are confirmed. As of CES 2026, LG, Samsung (which still does not support Dolby Vision at all), and Sony had not announced Dolby Vision 2 support for their 2026 ranges.

Dolby has not publicly documented new SMPTE ST 2094-10 metadata levels for Dolby Vision 2 as of April 2026, so whether DV2 changes the underlying bitstream/metadata schema or only the renderer side is not yet on the public record. Streaming-service DV2 rollout timing is similarly unsettled — CANAL+ has committed to delivering Dolby Vision 2 content, but Netflix, Disney+, Apple TV+, and Max have not publicly announced DV2 mastering or delivery timelines.
