Apple states you can return for normal wear and tear. Obv the second you unbox the phone, it's not the same condition you bought it in. Therefore it's completely 100% justifiable to return it for normal wear and tear which is scratches.
A quick google search shows that they don't say that at all. Before sharing false advice, it helps to cite the actual policy.
For any product in its original, undamaged and unmarked condition, simply return it with its included accessories and packaging along with the original receipt (or gift receipt) within 14 days of the date you receive the product, and we’ll exchange it or offer a refund based upon the original payment method.
