Is IPS LCD "burn-in" permanent?

[Shodan]

My phone has a small dark-ish line "burnt in" for a few months already. I'm aware of image persistence which is common on IPS LCD, but this one isn't going away. It's visible only on gray backgrounds.

I tried videos like this one a few times for about an hour each time, but it didn't help:

Should I keep it on longer?
Does it need to be at max brightness or is it all the same?
Should I try something else instead, like a static white image in full screen?

And most importantly, is it even actually possible to have a permanent "burn-in" on IPS LCD or can it always go away?

only 'fix' is to burn the inverted image that burned in to make it all burned evenly
or replace the screen+digitizer

test pattersn or cycling pixels does nothing

to help prevent burn, turn down brightness to 50% area or lower when it does not need to be bright
and disable always on display

Always and never are problematic. Sure it's possible, it depends on the details of what your phone screen is doing and why. If it's a major defect/failure, which is always possible, then obviously it would be permanent. And no amount of

In my experience those sort of fixes are kinda snake oil. If the issue is really specific, and not some sort of hardware failure then sure maybe it will help, or at worst not hurt (but not necessarily be the solution either). But in all other cases it's as worthless as healing crystals...

But regardless people:

1. Hope for the best.
   
2. Claim it doesn't hurt.
   
3. Assume it must help someone, at least once in a while.
   
4. And help spread it around.

I mean I've got a dead pixel. But there's always an off chance that it's just stuck right? So I jumped through the hoops, massaged the area, ran one of the color changer thingies (all night). If my pixel was just stuck, then sure maybe enough poking or prodding might help. But if my pixel is just dead, which is also very common. No amount of tricks are going to undead it.

You're going to have to decide for yourself whether your phone screen is temporarily defective, or permanently defective. I'd typically lean toward the latter. Since it's been a few months already I don't think you're likely to wake up tomorrow and find it operating like new...

fixing a dead/stick pixel by yourself is like trying to wake a long dead great-great-great-great-great-grandpa
poking the grave with a stick isnt going to do it

either a wire is broken/shorted, or the pixel is damaged
q/a should have caught it or it passed their min dead pixel req, (15 years ago many 720p lcd displays had a 5-10 dead/stuck pixel clause in their warranty that they would not cover)

I'm talking about LCD.

Well, I had at around 4-5 dead pixels on my new PC monitor when I bought it, I wanted to return it but apparently it wasn't enough to return it. Anyway, after a few months, I noticed that they just completely vanished on their own, all of them.

Also, those "tricks" actually work and make perfect sense. For example, Apple and Dell recommend them on their official support websites which definitely aren't some random sources.

Anyway:

It's a very short and a faint line, only visible on gray backgrounds and even then it's just slightly visible, but enough for me to see it.

It doesn't look like dead pixels (sharp), it's a bit blurry, more like a shadow, also it's not completely black.

I posted this because I'm not an expert and I'm not sure what exactly is the thing I described right above this sentence.

I get why these tricks would work and I do know many things about displays, but since I've never worked in a display factory or whatever, I have no idea what caused this and if it's reversible.

Look at the reply above.

Are you sure it's screen burn and not a fault? I had a 10.1" Samsung tablet replaced after almost a year of ownership because a fine vertical line appeared on the screen. I'm confident it wasn't screen burn.

Definitely, look at the first reply.

burned image and dead pixels have the exact same fix
replace the panel or display
