Readability of text is what I was talking about not just color contrast.
A lot of people assume that reading text is the same on all monitors,
it isn't and a lot of the pro level displays are better at this. Your free
to disagree that matters. However in my view it does help.

In addition I was also hinting at how well dpi is implemented at a higher
resolution, which does matter. Scaling for a higher resolution in text
is very much dependent on this. For whatever reason better dpi scaling
and text scaling almost always goes hand in hand with better color contrast.

My point is that most people focus on certain things like resolution
without all the details. This is similar to other things, maybe my
explanation was faulty.

Sorry for the misunderstanding,
