just to add my experiences.

i use a cheap Phillips TV it supports 12 bit input and is not chroma subsampling at all. the panel is clearly an 8 bit ips panel.

test picture set to video frame double size to see more banding.

FSE D3D11 10 bit
AMD set to 8 bit output no dither = clear high banding
AMD set to 10 bit output no dither= little banding
AMD set to 12 bit output no dither=little banding

8 bit window mode
no dither clear high banding
madVR dither=little banding

these dither "hacks" are set in the registry. without these hacks AMD set to 8 bit was still pretty good so the GPU can dither on is own with at least ok quality. but i will double check that later.

looks like my screen can use proper dithering
