I might be mistaken but I think it's the legit sticker.
Just an FYI, I have been successful in removing the Sony Warranty sticker completely intact. Meaning I have been able to place it back on the console and it look like the console had never been opened. The trick to hit is using a good hair dryer, or if you are really careful a heatgun that is used for Heat-shrink tubing. I have been repairing consoles for people for years and since the warranty sticker is there and in one piece Sony has been willing to repair a few of them that I was unsuccessful with.
