My insurer ended up replacing the replacement screen. The gist I got when digging around Google was that third party screen replacements have that side effect. It is pretty common for Apple to “accidentally” introduce side effects to third party parts. It was also quite obvious it was a fake as the chin said “Mac Book Pro” instead of “MacBook Pro”, and the backlighting had a stage light effect along the bottom (I.e. it was side lit instead of backlit like they’re supposed to be afaik)[br]

As the terms of insurance are to replace like for like, they had to take it back and fit a genuine screen.

I’ve dealt with them a second time now (butterfly keyboard issues and not eligible for repair program due to third party repair on the device). They tried to pull a fast one again and give me some weird Azerty/Qwerty mix someone had mashed together, they were once again told to take it back and replaced the laptop with another.
