I've seen severe CRT burn-in where text was in the same spot for prolonged times
- login screens to mainframes
- airport and train displays

VFD (Vacuum Fluorescent Displays) are also prone to burn-in.
I took some photos: ferretronix.com/tech/vfd

I still use one of these (albeit different button placement):

I estimate 35 years old. Is it less bright? Hard to say - I'm
that that much older and still looks fine to me.

Can't say the same for a Panasonic microwave fluorescent display
which is maybe 10 years old.
