Never had this problem. Might be related to GPU scaling or drivers. Do you have any color settings changed in your graphics drivers?

The only similar thing I experienced were games that changed gamma correction which temporarily overrides your windows gamma and color temperature settings. One example would be Unreal Tournament 2k4 (the editor for sure, I think the game does it too)
But this is independent of the resolution.

Edit: do you happen to have an HDR monitor? I never had one but people reported washed out images when displaying non HDR content using the monitors HDR mode.
