i have 7 test devices and only the pro motion panels have shown the issue for me. they are all on 16.2 and no user data loaded into them, fully erased and minimal setup to get to home screen.Unfortunately this issue also happens in my regular iPhone 13 without a pro motion display, so that might be only one of the problems. @MagicMiguel also mentioned that he saw it on a regular iPhone 12 and iPhone 14.
