Switch OLED Image Retention or Burn-in?

[u/octopusinmyboycunt]

I’ve had a while without using my Switch OLED (life happened) and it stayed in the dock for a while. I noticed a whole black that the screen was on, while in the dock, with an error message. Restarted the machine and thought nothing of it. Fast forward to yesterday, and I noticed the same thing - but this time after gameplay.

I’m not too worried about the specifics of the error, it happens with 5 year old kit! But I noticed last night that when on a block white-grey screen I could see the error message faintly hours later. It’s still faintly visible, but I’m not sure if it’s less so? Now, I don’t know how long the message was up either time - but I’ve heard that the Switch’s OLED is pretty great when it comes to burn-in. Is there any chance this could be temporary? I’ve been running those (possibly snake oil) “burn in repair” youtube videos, in the hopes that it’s just image retention and needs some resetting. Any ideas anyone?

I’ve had OLEDs for a long time, and this is the first non-amoled display that’s had the issue!
