You know, you can adjust brightness and gamma manually, either via your monitor, or your graphic card software.
With NVidia you can even save those adjustments as presets for each game.
I don't see the issue here.
That is not the way colors work on a display, if you do that then you will wash out all of the whites or any other bright colors on the screen. My monitor itself has quick settings buttons for different scenarios like that where you can customize settings (3 of them) but it wouldn't help in this case. straining your eyes to look for information that is a muted color on top of another muted color is a problem, it is also a problem to strain your eyes to try and read information that is far too bright.
Also because you do not see the issue, does not mean there is not one, so don't reply.
Fortunately it can be modded.
