That’s the real issue, isn’t it? The tooling for this is shitty. You can create an accurate color profile for your monitor, apply it in software and your OS will automatically map the values correctly. This will improve contrast quite a bit, but is complicated, expensive, and you’ll lose a lot of definition in other brightness ranges.

But the same issues apply in reverse if you try to reduce contrast because some idiot thought a 200:1 contrast for text was healthy.

My personal solution is relatively simple: I replace every monitor that’s too shitty to do sRGB at good contrast at 400 nits. For a T470/T480 I can recommend this panel: https://www.xelent-store.de/Innolux-N140HCG-GQ2-400cd-Low-Po...
