What kind of environment is that? Maybe if you're a black person wearing black clothes, no glasses (maybe contacts are ok?) in a room with closed curtains, no lights and nothing reflective, sure.
I used to daily drive an apple thunderbolt display (the last non-retina one, 2560x1440). That thing was atrocious. I could often see the reflections of my glasses, or a white glare if I was wearing a white shirt. At nigh, in a dark office (lights off, just whatever came in from the street).
I'm typing this on a matte "ips black" dell ultrasharp something-or-other at 10% brightness, wearing glasses, a white t-shirt, with an overhead light, and see no reflection or glare on my screen. There's no way in hell I'd go back to a shiny screen.
I understand "anti-glare" technology has improved. The most recent apple screen I've tested is an m1 mbp. It seems somewhat better than my 2013 mbp, but still a worse experience than my 2015 (or thereabouts) 24"@4k dell, which is pretty old technology. My 2025 lenovo has a screen that's much more confortable to use inside.
Paradoxically, I'd say the one environment where I prefer my macs to my matte screens is in bright sunlight. Sure, there are more reflections than you can shake a stick at, but there's always an angle where you can see the part of the screen you want. You have to move around, which is obviously annoying, but you can see. The matte screens just turn to mush. Luckily for me, I hate being out in the sun, so I never encounter this situation in practice.
I think the "frost" you're talking about depends a lot on the screen implementation. I tested once an HP model, 27"@4k, and it did have such an effect. Anecdotally, it didn't handle reflections all that well, either. So maybe it's just a question of lower quality product?
