Question [Q] Is this dust under screen?

Alright, I think a piece of dust is under my screen. The weird thing is I've never noticed it before, and I've had the phone for about a year. All of the threads I've seen on this issue is after someone just got their phone, is it possible a piece of dust got in there? Or maybe it's a pressure issue?

Also, to fix this would I just take it to verizon? And do I have to unroot?
