LCD Burn-In Just Won't Go Away

[Mac Guy Java]

My MacBook Pro (mid 2012) has display burn-in near the centre of the screen that I just can't seem to get rid of. I've tried all of those burn-in fix videos, and I've even left a white screensaver running for over 24 hours straight. My problem seems to be different from most I've encountered on my quest to fix this, as my burn-in is only noticeable on black screens and other very dark images. A plain white background or pretty much any other bright colour for that matter shows absolutely no burn-in. I've included images of my issue: one with noticeable burn-in, the other without.

This has left me quite worried, because most people claim their burn-in resolves after running a few fixes. Mine has not, which leads me to wonder if this is something other than burn-in, or if my problem is just too far gone to fix. All assistance will be greatly appreciated.

Might not be "burn-in", at all...
Maybe you have minor pressure damage to the screen, maybe even from hardware out of position inside the top, or from outside pressure when in a carry bag.

I agree. It looks like pressure damage on your screen.

LCDs can't burn in as they're not light emitting, where something like a CRT or Plasma can. In very extreme cases LCDs can get image persistence but it usually goes away.

From those photos unfortunately I can't see the problem.

As above, possible the lid is warped/damaged which is applying pressure to parts of the screen.

That's pressure damage, not burn in. The LCD at that portion is not able to display black properly now.
If it's burn in (which will not for LCDs), the blue will remain when you change to a white background.

So it's pressure damage then. Is there any way to reverse this?

Replace the screen.
