Is yuv422 better than RGB? YUV color-spaces area more efficient codingand reduce the bandwidth more than RGB capture can. Most video cards, therefore, render directly using YUV or luminance/chrominance images. The most important component for YUV capture is always the luminance, or Y component....

but under Nvidia control panel i changed the option to 'Use Nvidia colour settings' and played around with 'Desktop colour depth' (only option is 'Highest (32-bit)), 'Output colour Depth' ( 8bpc / 10bpc), 'Output colour format' (RGB / YCbCr422 / YCbCr444) and 'Output dynamic range...
In theory, yes it can take a YCbCr and convert it to LAB from which it then converts it to RGB using its LUTs to ensure the targeted display is displaying the original YCbCr image correctly. But it cannot offer any insight into the condition of that monitor. Nor will it stop your work...
