Dolby Vision Profile 5 vs Profile 7
Also known as: dvhe.05 vs dvhe.07, Dolby Vision single layer vs dual layer, Dolby Vision Profile 7 FEL MEL, Dolby Vision profiles explained
Dolby Vision Profile 5 (dvhe.05) is a single-layer 10-bit HEVC stream in Dolby's proprietary IPTPQc2 color space with no HDR10 fallback, used for streaming. Profile 7 (dvhe.07) is the dual-layer Ultra HD Blu-ray profile: an HDR10-compatible base layer plus a minimal (MEL) or full (FEL) enhancement layer. Profile 7 falls back to HDR10 on non-Dolby displays; Profile 5 does not, which is why most Dolby Vision files shared on home servers are converted to Profile 8.1.
What Profile 5 and Profile 7 are
Dolby Vision is not one bitstream but a family of profiles. Dolby's Profiles and Levels specification (V1.2.93, April 2018) defines each as a video codec profile plus signaling metadata plus Dolby Vision composer and content metadata. Profile 5 has the string dvhe.05, 10-bit HEVC, no enhancement layer and a base-layer cross-compatibility ID of 0, meaning none. Profile 7 has the string dvhe.07, 10-bit HEVC, a base layer and an enhancement layer, and a cross-compatibility ID of 6, defined as Ultra HD Blu-ray Disc HDR per the Blu-ray Disc Association standard. Wikipedia lists the same pairing: Profile 5 with no backward compatibility, Profile 7 for Ultra HD Blu-ray.
How the two architectures work
Profile 5 is one video layer. The spec says a Profile 5 stream must use perceptual quantization with reshaping for the transfer function, Dolby's proprietary IPT for color primaries and matrix, full range and center-left chroma siting, and it describes the IPT space as similar to BT.2100 ICtCp. Its VUI values are 2,2,2,1,0, which H.265 reads as unspecified, so a generic decoder has nothing to interpret. OSMC, which makes the Vero V player, calls it "optimised for efficient streaming," with one layer in an IPT-PQ-c2 colorspace that must be converted before it can be sent over HDMI. JellyWatch reports that the image looks washed out on a non-Dolby display.
Profile 7 is two layers plus metadata. Its base layer carries VUI 16,9,9,0,2, which in H.265 terms is PQ transfer, BT.2020 primaries and matrix, limited range and top-left chroma siting, per the Blu-ray specification. The base-to-enhancement resolution ratio is 1:1/4 for UHD and 1:1 for FHD, and base layer and enhancement layer must be fully aligned. Wikipedia says the two layers combine to a 12-bit stream. The enhancement layer is either minimal (MEL) or full (FEL). Dolby defines a MEL as composer and content metadata for a mid-gray flat-field sequence, and OSMC explains that a FEL carries a video stream that modifies every pixel of the base layer while a MEL is equivalent to Profile 8.1.
Profile 5 vs Profile 7 head to head
Both carry dynamic metadata; the differences are structural. Profile 5 has no fallback, so a display without Dolby Vision cannot render it correctly. Profile 7's base layer is a standards-based signal, so a plain HDR10 display shows the base layer and ignores the rest. Dolby's level table caps bitrate by level: Level 06 (3840 x 2160 at 24 fps, 199,065,600 pixels per second) allows 25 Mbps in the main tier and 130 Mbps in the high tier, while Level 09 (3840 x 2160 at 60 fps) allows 40 Mbps and 130 Mbps. For Profile 7, the Blu-ray Disc Association limits the high tier to 100 Mbps. A typical Profile 5 stream is described as dvhe.05.07, a pixel rate up to 248,832,000 per second (3840 x 2160 at 30 fps), and a typical disc stream as dvhe.07.06.
Where each profile lives and what plays it
JellyWatch names streaming WEB-DL files from Netflix, Disney+ and Apple TV+ as typical Profile 5 sources, and Son-Video says single-layer Profiles 5 and 8.x are widely used by Netflix, Disney+ and others. Profile 7 comes from discs; Son-Video calls UHD Blu-ray the best Dolby Vision source because the FEL variant carries more than streaming's simplified version. JellyWatch's June 2026 compatibility table says Profile 5 direct-plays on Apple TV 4K, NVIDIA Shield TV, Fire TV Stick 4K Max, Chromecast with Google TV, LG C-series OLEDs and Roku Ultra (2022 and later), but not on Samsung Tizen TVs (which use HDR10+, not Dolby Vision) or in a PC web browser. For Profile 7 FEL and MEL it reports a fall-back to HDR10 on Apple TV 4K, Shield, Fire TV Stick 4K Max and built-in Samsung and LG apps, with full Dolby Vision on a CoreELEC Ugoos AM6B+ and the OSMC Vero V. OSMC says Vero V passes Profile 7 through to Dolby Vision displays, merging the dual tracks into one.
Conversion and fallback
Profile 7 can be reduced to Profile 8.1, which is single layer with an HDR10 base. The open-source dovi_tool lists a mode that converts the RPU to Profile 8.1 and removes luma and chroma mapping for FEL, a MEL-compatible mode, and a separate mode that converts a Profile 5 RPU to 8.1. Converting a MEL is straightforward because it contains no extra picture data; converting a FEL discards enhancement information. See Dolby Vision Profile 8.1 for the compromise format and player-led Dolby Vision for what a player does when the display lacks Dolby Vision.
Common confusions
"Dolby Vision" on a streaming tile does not tell you the profile, and Dolby's spec does not assign profiles to services; the Netflix, Disney+ and Apple TV+ attributions above come from secondary sources. A Profile 7 disc is not "better Dolby Vision" in every scene: with a MEL the enhancement layer adds no picture data, as OSMC notes. And a Profile 7 file may play only as HDR10 even on a Dolby Vision TV when the playback box cannot decode the dual layer, as JellyWatch's table shows for the Apple TV 4K, Shield and Fire TV: the player, not the display, is the limit. For the format family see Dolby Vision, HDR10 and Ultra HD Blu-ray, and for the next generation read Dolby Vision 2.
