HDR format: Dolby Vision, Version 1.0, dvhe.08.06, BL+RPU, HDR10 compatible / SMPTE ST 2094 App 4, Version 1, HDR10+ Profile A compatible
Dolby Vision = No
HDR10+ = No
HDR10 = Yes
HDR = Yes
TL/DR; ^ the static formats are supported, the dynamic and proprietary ones are not. I'll also caveat that right now LE/Kodi (on Linux) have reached the "HDR support v1.0" milestone, and maybe v1.5 on RPi4 which has more plumbing for colourspace and bit-depth wired up. HDR support still needs more things in the Linux kernel to be agreed upon, and should hopefully improve with related planned changes for Kodi Omega (v21).
