Hi, I've got a suggestion for this feature: show that better color modes could be enabled for a given resolution by changing the refresh rate.

I was able to finally (after an year or so!) figure out why my monitor was only negotiating YCbCr 4:2:2 by checking the connectionModeListAll CLI command and seeing that RGB would be available by using 60 Hz as the refresh rate when using its native resolution.

/Applications/BetterDisplay.app/Contents/MacOS/BetterDisplay get -namelike=dell -connectionModeListAll | grep 3440x1440
2597591175131565424 - 3440x1440 99.98Hz Fixed 10bit SDR YCbCr 4:2:2 Limited SRGB
2561562378112601456 - 3440x1440 99.98Hz Fixed 8bit SDR YCbCr 4:2:2 Limited SRGB
3010514649749130608 - 3440x1440 59.97Hz Fixed 12bit HDR10 YCbCr 4:2:2 Limited SRGB
2704269875087936880 - 3440x1440 59.97Hz Fixed 10bit SDR YCbCr 4:4:4 Limited SRGB
2596183484031044976 - 3440x1440 59.97Hz Fixed 10bit SDR YCbCr 4:2:2 Limited SRGB
2560154687012081008 - 3440x1440 59.97Hz Fixed 8bit SDR YCbCr 4:2:2 Limited SRGB
1227089197310414192 - 3440x1440 59.97Hz Fixed 10bit SDR RGB Full SRGB

Edit: I just had to mention I'm so happy that I'm now able to finally use RGB with this monitor that I bought a license. It's the least that I can do to thank you.

Ok, for some reason even though I added this feature to v3.0.5, I failed to enable it... So it's going to be in the next release. :)
