This sounds more like a black level issue on Nvidia cards. If the black level is wrong the picture will look washed out.
AMD cards probably run the opposite black level to Nvidia so I recommend messing around with limited and full setting if your using RGB( also bare in mind you may have to change the settings twice and a reboot for the change to stick ).
Also change the black level settings on the TV or monitor if the driver settings fail to work.
I personally use 422 10 bit - everything looks vibrant and crisp on my oled TV with Nvidia card. If someone told me otherwise then they got poor eyes.
Just to add I don't use digital vibrance, tv has been calibrated too. I would say Forza Horizon 4 I'm HDR has probably the widest and most natural looking colours in any game. Good game to use as a test for screen settings
