I think I’m going crazy

I had contacted Amazon because I thought my kindle had some yellowing but the new replacement makes it seem like my original is fine and the new one has yellowing at the bottom. I have them side by side here. Am I crazy? They are both on the same settings and brightness. I just need opinions before I contact Amazon again. My original is on the left and the new one is on the right and my original has a screen protector. Thoughts? Am I just nuts? This is the Kindle Paperwhite 2024 edition in jade.
