Ah, thanks for the link. The story this post is linked to said only aftermarket screens had this issue.
I don’t have any inside knowledge but I suspect authorized Apple repair centers have access to a tool they can use to recalibrate the screen after replacement that the mom-and-pop shop doesn’t have.

A genuine screen from another iPad will cause this issue until you swap the chip from the old screen to the new screen.
