Let’s not forgot about scratched frame. One of mine was pitted and really bad out of the box on the rim of the gold frame above the lightning port. QC is terrible.Yea that is why if its something small I wouldn't want to replace it, because there could be something worse like that green tint or yellow tint or a dead pixel..... The gap is very small year dust can be noticeable just wipe it with a microfiber towel and it will go away or use a thin paper to take the dust out of course if a coin fits in the gap then yes replace it but not because thin paper fits lol...
