that isn't normal. I could understand if this is older and in high heat environment. I would expect this only in laptop that is some years old from heating up and cooling down releasing the glue. You indicated this is new, so probably bad fabrication. It is aesthetically unpleasing. Most people buy this laptop because of the high aesthetic value, if it doesn't please you I would try to exchange it. It wouldn't bother other people probably so this is a preference choice.
If it was me I'd be very annoyed and try to exchange it. If it was my husband I know he wouldn't give a crap and keep it.
Up to you!
