Nvidia pushed an update January 5th 2026 ( the day you posted ).
Should Fix most of what your talking about, As they just added support and compatibility for a large amount of things.
Use the Nvidia App to do a clean installation.
With the nvidia app > ( left panel ) click system, then for the display tab, you should see a dropdown for the color section,
Most of the drop down boxes should be greyed out, But you can click all channels or red specifically and adjust a few different things.
^ But like i said this latest update, should fix a lot of what you just described automatically.
