I plan to investigate this a bit further and more thoroughly (including the use of a DSLR instead of a smartphone camera) at a later date but here is an example of under-saturated HDR colors with AMD (-> see the attachments).
When the AMD output looks like this the TV's OSD info banner does not list Rec2020 (though no Rec709 or other standard either, the list is just shorter) whereas Rec2020 appears with nVidia and also with AMD when it happens to function as expected (nVidia seems to be reliable nowadays while the AMD is a random coin flip, sometimes it's fine, other times it's bad, I don't have enough data to tell what could cause this if there is any specific trigger).
And yes, now I am aware DXVA2 is broken but that "only" causes banding (a lot with AMD, a little with nVidia), not color gamut mismatch. I switched to D3D11 decoder on both systems by now.
