OCD? I have OCD and used to return things for not being perfect a lot, though the most I ever did was I think 3 returns for a phone I really wanted to like (a Lumia), but all 3 had dead/stuck pixels. I bailed on it and got an iPhone after the third try
One thing that’s helped me with this is naming my devices when I get them. It makes it harder for me to want to return them for something minor, & easier to accept their blemishes. I put their name in the about section where it’s normally “sleep’s iPhone 13” or whatever
Reality is, nothing in the physical world is perfect. Try to embrace the idea of wabi-sabi
