Samsung QN85D game mode HDR switching bug

Hi!

I recently bought a QN85D TV. The only problem I have is that in game mode it doesn't switch between HDR and SDR normally for the same source. If I switch to HDR, the SDR brightness and contrast remain and vice versa when i switch back from HDR to SDR max brightness remain etc. (PS4, PC doesn't matter) The HDR icon itself appears, the gamma also switches, HDR tone mapping becomes available and so on, but i have to adjust the other settings manually. I am on the latest firmware (1201.8).

It seems that the above phenomenon only occurs when game hdr (HGIG) is disabled. In this case, the TV adjusts the white balance set in HDR filmmaker mode with HDR gamma, SDR brightness and contrast. When game HDR is enabled (basic/advanced), it is treated as a separate picture mode and switches between them correctly, remembering the set values.
