Went and measured just now, I'm about 27 inches away from my screen sitting normally, 45 inches when leaning back and about 20 inches leaning in.

I've legitimately never noticed a difference in any of those positions. Maybe I need better glasses if you swear you can tell a difference on your 27" one from about 36 inches away? I’m only in my 30s so if you were significantly younger than that or if you don’t need glasses and that might be why lol
