As with paint missing from leg sockets, they aren't going to cover smaller cosmetic issues like this. But damn if that don't look pinkish instead of red. And the rust on the lip is something you only see after some use. Their painter truly found a way to save money by applying the thinnest amount they could get away with.
At this point, I'd use the snot out of it. Make it your daily cooker. Somewhere between now and 10 years, you've got additional claims you can make. But keep in mind, they don't warranty against rust. They warranty against rust-through, if I'm not mistaken.
