Dropped my Kobo Libra and now I'm freaking out

I only bought it recently and started using it three days ago. Today my sibling dropped it from the bed and while it has a sleepcover and works well, I think there are these tiny spots of light on the bottom that I noticed between the screen and plastic and they're bothering me. They're not visible when I'm reading but once I look at it horizontally it bugs me a lot.

Is that a problem or common for Kobos?
