Somebody drank its portion of cool aid for sure. There is that little detail that glossy screens needed absolutely perfect conditions in front of them to not reflect literally whole world, making resulting visuals often subpar to matte. I have never, ever been in work conditions in past 20 years that didn't manifest this in annoying and distracting way.

I haven't seen a single display that ever overcame that properly for long term work. Sure, phones use it but they increased luminosity to absurd level to be readable, not a solution I prefer for daily long work.

I admit there are corner cases of pro graphics where it made sense (with corresponding changes to environment) but I am not discussing this here.
