MPC Video Renderer (MPC-VR) v0.4.10.
1542 https://yadi.sk/d/X0EVMKP4TcmnHQ/Old/0.4.10 (0.4.10.1542 is last version let turn HLG processing off in MPC-VR and well use HLGtoSDR shader instead) shows HLG on SDR even better than shaders on my own.
With MPC Video Renderer colors are less saturated but nearer to SDR.
