hi there,
using current K-Lite Codec Pack MPC with madVR for HEVC 2160p Video the Color Controls are not working. No Problems playing AVC 720p.
This is not a specific Problem of MPC only, since it also appears with VLC and Pot Player. Guess there is some Stream Protection happening since the Content is HDR. The Video shows too dark, Brightness Control is needed.

Format profile              : Main 10@L5.1@High
HDR format                  : SMPTE ST 2086, HDR10 compatible
Codec ID                    : V_MPEGH/ISO/HEVC

Options->Playback->Output->madVR is set for DirectShow Video
Options->Miscellaneous->Color Controls 2160p-not working/720p working

Format profile              : Main 10@L5.1@High
HDR format                  : SMPTE ST 2086, HDR10 compatible
Codec ID                    : V_MPEGH/ISO/HEVC

It if does not work it is the driver's fault. It may be possible that it intentionally disabled it when outputting HDR.

You could try letting madVR do the tonemapping instead of the TV.

madVR settings > devices > HDR > tonemap using pixelshaders
and the adjust "target peak nits" value. Lower value should give brighter picture. For example try 150. If even 100 is not bright enough, then something else may be wrong. In that case press Ctrl+J to view madVR statistics overlay and check if it gets proper HDR metadata.

I just tried on my system (with NVIDIA GPU) and here it also doesn't work with madVR for HDR video. Also not even with madVR's internal brightness shortcut set. So it might be a bug in madVR.

It does work here with "MPC Video Renderer".

Make sure that all color control related options in the AMD driver settings are disabled. Because if any of those are enabled, it will ignore the settings from the player/renderer.

I don't have a solution for you. I can only suggest to try different driver versions.
