I think Apple doesn’t officially offer parts to anyone but their authorized repair people. So, the part you’re getting is either “acquired via ‘other’ means” or just labeled Apple Certified without actually being certified. There have been other parts where, once swapped, the OS will inform you that it’s not an Apple Certified part. Which, if it’s your own, well, duh, you don’t care you knew it when it was put in.Has this ever been the case, assuming using Apple parts?
For folks that want to swap in questionable parts and still sell an Apple device as simply “used” without telling the buyer, they don’t like it for obvious reasons.
