I would post those exact results in the Doom9 forum. madVR can't be eliminated because switching to 10-bit output is causing the problem.

It will be simpler to understand if BT.2020 wasn't correcting the problem. The AMD driver might not know what to do with a 10-bit BT.709 SDR source.

I would also add:

Direct3D 11 + madVR (10-bit) + BT.2020 + AMD (10-bit) =  normal (BT.709)

Thanks but I've ruled out MADVR if you remember, I've now managed to reproduce it in MPC BE with the standard renderer in DIRECT3D 10 bit output mode, it has to either be Windows 10, DIRECT3D or the AMD driver which is why I logged a ticket to AMD again. I asked MADSHI to pass the issue to any contacts he might have had at AMD but he must be busy as he hasnt been on the forum for a while.

Best MADSHI could do is maybe have a toggle in MADVR for AMD users to fix this problem as he does have workarounds in there for some NVIDA isues I think.   

 You could simplify your explanation of the problem to AMD like this:

When using madVR for video playback, BT.709 SDR content is not being passed through to the display with the correct color.

To reproduce:

 (madVR - general settings) use Direct3D 11 for presentation (Windows 7 and newer) + (madVR) 8-bit + (madVR - calibration -> this display is already calibrated -> primaries) BT.709 + (AMD) 8-bit = normal (BT.709)

(madVR - general settings) use Direct3D 11 for presentation (Windows 7 and newer) + (madVR) 8-bit + (madVR - calibration -> this display is already calibrated -> primaries) BT.709 + (AMD) 10-bit = normal (BT.709)

(madVR - general settings) use Direct3D 11 for presentation (Windows 7 and newer) + (madVR) 10-bit + (madVR - calibration -> this display is already calibrated -> primaries) BT.709 + (AMD) 8-bit = not normal - oversaturated

(madVR - general settings) use Direct3D 11 for presentation (Windows 7 and newer) + (madVR) 10-bit + (madVR - calibration -> this display is already calibrated -> primaries) BT.709 + (AMD) 10-bit = not normal - oversaturated

(madVR - general settings) use Direct3D 11 for presentation (Windows 7 and newer) + (madVR) 10-bit + (madVR - calibration -> this display is already calibrated -> primaries) BT.2020 + (AMD) 8-bit/10-bit = normal (BT.709)

Summary: 10-bit SDR output from the media player with Direct3D 11 presentation enabled is producing the wrong colors. 

I would also mention the other media player with the same problem and attach the image that showed the corrupt color.
