The issue doesnt seem to happen with 4K h264 bt709 files, only with Youtube VP9 4K content. I played a 4K h264 file (59.94 fps, bt709- recorded gamplay on pc) and the color range remained correct at bt709.

What do you mean by seeing a difference, in terms of sharpness? Sure I can see the difference between 1440p and 4K, even with youtube videos. After all 4K has over 2x as many pixels as 1440p.

What would also be interesting if someone could test a 1080p HDR rec2020 file, if the color switches properly. I dont have such file to test, if someone can point me to a download of a test / demo video with 1080p 10/12 bit HDR rec2020 I can test it if it works correctly.

Other than that- I dont have an account on the Nvidia Forums and dont really intend to create one, so if one of you does have an account on NV forums, feel free to post the bug with 4K VP9 bt709 (both 30fps and 60fps) beeing color switched incorrectly to rec2020.

You can show them this picture and they should figure out everything by themselves:

edit: 1080p HEVC HDR works correctly as well, switches to rec2020 properly.
