WTF! No, that is NOT how that works.

The image is there because the OLED pixel for that image was been either on or off all the time. So now it is either brighter or dimmer than the other pixels around it. Same as what use to happen to plasma TVs.
The brightness vs. life span of the pixels is not linear. They wear faster when new and slowly taper off with brightness vs. age.
So the fix for image retention / burn-in, is to wear all the pixels in the area to make them closer to the same. That is what many of the built-in patterns try to do to the TV.
Understand that this is over all dimming the TV more. And it is not a perfect fix because the uneven wear is always there. And if it is severe enough, no amount is going to fix it - ever.

The ideal solution that WOULD fix the TV, is to have a negative image of what it 'burned in' to the TV and display that for many hours. That would only wear the pixels needed to even everything out. This of course is a lot more complicated to do and requires image capture and software from a media player to accomplish.

Ideally if manufacture were smart, along with the basic test pattern for screen burn-in some of them supply, they would have a option for negative display. Where a customer could put the TV on the offending channel, switch the negative display feature on, and let the TV run for several hours each night while they are sleeping. It would do a much better job at fixing the issue.

true dat!
