I'm seeing a lot of problems with OLEDs in terms of
- lots of flickering (100-200 Hz with extremely short ON time in these
strobe bursts)
- lower intensity on a pixel row if many pixels on the row are lit
- burn-in, causing the most used pixels to fade after time

Are you really sure that it changed the 1st and the 3rd issue above at all?

I'd suspect a less perfect power source could be causing the 2nd issue (not
having enough power to light up a whole row), but I wouldn't expect it to
affect the display update rate (1st) or the aging of materials (3rd).
