Gaps between screen and case

Gaps between screen and case, at the top of the screen there is a strong gap that catches the eye, even the glue is visible in places, when I called the service center, they told me that it does not fit under the warranty case, and Apple does not recognize this as a marriage.

At the same time, I read forums from people with the same problems, and users changed their smartphone to a new one without question, is this considered a normal screen condition, or is it a smartphone replacement? Maybe it's some incredible technological features of the screen...?
