hiii, I noticed a strange "holographic" or ghost-like pattern permanently stuck on my iPad Air screen. At first, I thought it was just a wallpaper design or part of the iPadOS UI, but even after changing the wallpaper to a solid flat color, the lines and shapes are still there (visible on a blank/gray screen, as shown in the photo).

Has anyone experienced this before? Is this screen burn-in, image retention, or a hardware panel defect? My device is still under the Apple Limited Warranty. Will Apple cover this type of screen issue? Thanks for any advice!
