On HDR10 displays that have lower color volume than the HDR10 content (for example lower peak brightness capability), the HDR10 metadata gives information to help adjust the content. [6] However, the metadata is static (remain the same for the entire video) and does not tell how the content should be adjusted.
HDR10+, also known as HDR10 Plus, was announced on 20 April 2017, by Samsung and Amazon Video. HDR10+ updates HDR10 by adding dynamic metadata that can be used to more accurately adjust brightness levels up to the full range of PQ code values (10,000 nits maximum brightness) on a scene-by-scene or frame-by-frame basis.
Lighting precision was confined to 8 bit integers, which limited the contrast ratio to 256:1. Using the HVS color model, the value (V), or brightness of a color has a range of 0 – 255. This means the brightest white (a value of 255) is only 255 levels brighter than the darkest shade above pure black (i.e.: value of 0).
The highlights—the brightest parts of an image—can be brighter, more colorful, and more detailed. [2] The larger capacity for brightness can be used to increase the brightness of small areas without increasing the overall image's brightness, resulting in, for example, bright reflections from shiny objects, bright stars in a dark night scene, and bright and colorful light-emissive objects ...
It is the responsibility of a manufacturer of vehicles and/or vehicle lamps to certify that each motor vehicle and/or lamp is in full compliance with the minimum performance requirements of FMVSS 108. This is a self-certification process as opposed to the type approval process which is used in other lighting regulations such as UNECE Regulation 48.

Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. [1] [2] [3] It covers content creation, distribution, and playback.[1] [4] [5] [6] It includes dynamic metadata that define the aspect ratio and adjust the picture based on a display's capabilities on a per-shot or even per-frame basis, optimizing the presentation.
