Seen on Fox's UHD Blu-ray releases (Taken from The Martian) Like I described in my Paramount upload, the video files on most UHD BD releases are HDR optimized. If you're watching this on a non-HDR display, you will see that YouTube has "downconverted" the HDR to SDR so the colors won't appear washed out. Seeing as only some discs are able to have their protection decrypted, and the fact that I only have a few UHD BD discs, it may take some time before I cover something else on UHD BD.
