Is this screen damage repairable?

That looks like trapped water / moisture between the cover glass and the actual LCD.

First be certain the screen functions in that area: open “something” and drag into / through the area. That I can see the “settings” and “terms” text in your pict is hopeful.

Grab a hair drier and WARM it from center to outside.

If image ok, leave it up while warming. You “should” see the fogged area receding.

Don’t get it hot, don’t try to fix it in one pass.

You’re forcing evaporation and it won’t always go where you want. Patience isn’t a virtue here, it’s a necessity.

Also literally inverting the unit may have allowed water to enter the screen space. Any keyboard contamination should be to hold the keyboard off vertical away from the circuitry area and the screen Way above it. Awkward as it is at this angle, Shut It Down.
