Thanks for your time,

Genuine Burn-in is "permanent," and so, NO, a few hours of slides presumably would do no good.
Odds are better that what you have is Long-Duration IR, which will fade with OTHER usage of the panel - that is, usage that does NOT display the same static image that caused the IR in the first place!
If you Search about, you will find various approaches to dealing with IR - not counting Ignoring It, or throwing the panel out the window (literally or figuratively)....

Simply watching Full-Screen NO-Static-Images content will eventually cause the IR to fade. For a quicker approach, you can try the built-in white scroll bar (but watch the time limit on it!) - but, frankly, if the white bar gets rid of the IR within its 15 (20 - ?) minute time limit, your panel does not have a very severe case of IR.
Could also try a "pixel flipping" utility (Disney WOW perhaps - ?); try running the slides, but in a random, short-duration mix; or try some full-screen animation material (we usually Zoom these to the max - keeps logos off screens, but also there generally tends to be more movement in the center screen areas than around the edges).
Alas, simply running WHATEVER for a few hours, and then returning to the Same Static Image that originally caused the problem - leaving THAT up for some hours - is likely to leave you with the same IR. It might take a fair amount of time WITHOUT that same Static Image for the pixel to "recover."
IF you are "lucky" - as reports vary from owner to owner, so it is hard to know what
else to attribute IR differences to - your panel will become more IR "resistant" as it ages.
Can you change the Location, Color, or Brightness of the offending image?
