I'm running on an AMD 460 so cant test i'm afraid but when I play HDR movies using the windows FILMS a& TV app with the windows HDR toggle on they look very similar to the output of MADVR suggesting an NVIDA HDR issue to me.

Not sure why you 'd want to run HDR that way though, but I know there have been some issues getting HDR to work properly with some NVIDIA driver versions, AMD has been working fine with HDR for a long while now but did have some issues with earlier RX 4XXX drivers if memory serves.

AMD is pretty much play and go at the minute for HDR, no issues at all. I'd like to move to the more powerful NVIDIA cards myself but there are just too many issues, just dont think NVIDIA put the time in to HTPC playback AMD does.
