[Q] Cracks behind screen?

[NeoMeir]

So I'm not sure how these happened but I've been noticing some (what looks like) cracks in my screen. The odd thing is I've never dropped this one (as of yet) and the cracks are only visible when I'm in a dark place and the color over the "Cracks" are black or dark grey. Does anyone have any idea what these are or how they got there? I would take a picture but they really are not visible except in the dark. The most common time I see them is when I get the loading screen for netflix. They seem to be all around the edges with one or two small ones towards the center.

Thank you in advance for any insight into these I just want to figure out this mystery.

Also I'm wondering if this could be a defect of some nature and if so I will take it back to AT&T but I only have another month to figure this out.

Nobody at all not even a suggestion/theory?
