If you have a $200 monitor then it probably struggles to make proper use of 8-bit formats. I have a display that claims to simulate DICOM but it's not enough I want more. However I'm not willing to spend $3000 on a display which doesn't have engineering specs and then send it back because it doesn't work. I don't care about resolution. I care about being able to see the unseen. I care about edge cases like yellow and blue making pink. That was the first significant finding Maxwell reported on when he invented RGB. However nearly every monitor ever made mixes those two colors wrong, as gray, due to subpixel layout issues. Nearly every scaling algorithm mixes those two colors wrong too, due to the way sRGB was designed. It's amazing how poorly color is modeled on personal computers. https://justine.lol/maxwell.png https://justine.lol/maxwell.png

Well, when released in 2008 it was a $600 monitor, I got it second-hand for 80€. I'm not sure what DICOM has to do with color reproduction quality ? Also it seems to be a quite a bit older standard than sRGB... By definition, you can't "see the unseen". "Yellow" and "blue" are opponent "colors", so, by definition, a proper mixture of them is going to give you grey : https://www.handprint.com/HP/WCL/color2.html#opponentfunctions https://www.handprint.com/HP/WCL/color2.html#opponentfunctio... Also, when talking about subtle color effects, you have to consider that personal variation might come into play (for instance red-green "colorblindness" is a spectrum).

  It looks like this thing is the thing I want to buy https://www.apple.com/pro-display-xdr/ https://www.apple.com/pro-display-xdr/ There's plenty of light that is currently unseeable. Look at chromaticity chart for sRGB. If your definition of color mixes yellow and blue and as grey then you've defined color wrong, because nature has a different definition where it's pink. For example the CIELAB colorspace will mix the two as pink. Also I'm not colorblind. If I'm on the spectrum I would be on the able to see more color more accurately end of the spectrum. Although when designing charts I'm very good at choosing colors that accommodate people who are colorblind, while still looking stylish, because I feel like inclusive technology is important.
