Yeah, according to DF, most upgraded switch 1 games have forced HDR, but Nintendo didn't or couldn't change the tone mapping to match The higher range of colors, so the colors look  washed out. Apparently, super Mario Bros U and splatoon 3 don't do this; they only display properly in SDR mode when you have the "only compatible software" option on.

I've never messed with any HDR settings on my games. Never thought to do it.

Weird, I didn't see any problem with Mario Odyssey.

Cyberpunk 2077 allows you to make a very simple change to HDR. There are actually 4 settings to change but only 1 is needed. Its the slider where you choose between a darker more colourful look or brighter washed out one.

And you can immediately see the result and go back and change it. Other games rely on the system level setting and different games behave differently with it. I gave up after a while.
