Aura Kobo Aura screen irregularity

Hi,

I bought an Aura just the other day and the screen appearance is not uniform. I've tried to capture it in some pictures but it is difficult.

The top had a bar running across it, while the right side looks fine for the top half and then at the bottom half, and running around the corner to the bottom, there is another darkish line.

It doesn't seem normal, although it's the only Kobo Aura I've ever seen before.

Thanks in advance for any help.
