Go to the nvidia control panel and simply check if Output color depth is set to 10/12 bit...

If I remember correctly, madVR should switch to 10/12bit if you switch to it manually once... I could be wrong...

So somewhere its either getting converted to 8 bit or a lower chroma? It plays fine and looks very good to my eyes, but I 'need' to know if some unnecessary conversion is getting done somewhere. Madvr OSD says P010, 10-bit, 4:2:0 but I am not sure if that's what the GPU is finally passing to the panel?
HDMI 2.0 supports up to 4K 60Hz 4:2:2 12bit, so set that if you are playing that file... also there's a 99% chance that your file is a test video, there probably will be one movie in 4K 60fps in the next 10 years, so you really shouldn't worry about 60Hz now...
