Samsung and Amazon join forces to add yet another HDR standard in the video mix-- HDR10+, an option the two giants say is better than the rest through a free and open nature.
As the name might suggest, HDR10+ is similar to the current HDR10 standard, but it does have a few differences. The chief addition is Dynamic Tone Mapping, a means for HDR-capable TVs to adjust brightness on a scene-by-scene or even frame-by-frame basis, producing "images that are much closer to the director's intent."
Dolby Vision already has such a dynamic metadata setup, unlike HDR10 which is stuck with static metadata. One has to point out Dolby Vision supports HDMI 1.4a and upwards, while HDR10 requires HDMI 2.0, but HDR10+ does not require TV makers to pay licensing fees.
