I went to the Apple store yesterday to trade in my iPad Air 2 since I bought a 12.9 inch 3rd gen pro. The air 2 was a refurbished since the last one had display issues years ago. I already had it restored ready to go went up to a specialist. He checked it out to make sure it worked. But then noticed the light bleed. He checked with the guys over at the genius bar and came back and they all said it was a third party display And that I couldn’t trade it in. I let him know it wasnt a third party display and the light bleed got worse over the years. So I showed him my receipt from the Apple store in Germany. They looked it over even thought it was all in German. His coworker saw the replacement price and how Apple gave it to me as a replacement and did the trade for me. don’t they have equipment that tells them if it’s a 3rd party display or not?
