I have a VA monitor that I bought in ~2019 with -according to its service menu- just under 40,000 hours of backlight-on time. It has some small hemispherical darkening along the top of its left edge that you can only notice when that portion of the screen is bright but has zero burn-in. [0] I use it for both video gaming and ordinary computing tasks.

[0] This darkening corresponds to nothing I've had on screen... it looks like the sort of minor backlight or diffuser (or whatever it's called) failure you tend to see on middle-aged monitors.
