Apple's Studio Display has a “nano‑texture glass” option, which is designed to reduce reflection/glare, but also subtly-but-noticeably blurs the image.

Looking at them side by side, I somewhat preferred the blur/bloom of the nano‑texture glass, perhaps due to retro CRT nostalgia. At 5K it's still incredibly crisp compared to 1x pixels (e.g. 27" 1440p).

(But… for looking at code/text all day in a room without ambient lighting problems, I chose the crisp image of the plain (antireflective-coated) glass instead)
