Strange white “ripple” behind display appeared today

Today I noticed that there’s a small ripple/smudge shaped bright spot on the left edge of my display. You can see it on the photo below but in real life it’s more noticeable. It appears to be behind the glass and it is only visible from certain angles, a bit like a hologram. It’s only visible on bright backgrounds. It’s not worn screen coating as it even appears to be behind the screen contents.

MacBook Pro 16 inch Intel 2019.

I have AppleCare, so I wonder if they would consider fixing something like this. I’ve always been super careful with my machine and I’ve never dropped or even bumped it against anything, I always use a soft case and I keep it on my desk most of the time.
