I wouldn't worry too much about it. I wanted to remove it and mod it somehow to make it sit flat like the sim tray but chances are it'll break.

I've also checked a few of the reviews of the phone and its the same. I think yours looks more accentuated due to the lighting in that photo.

Look at my post here. You can see it a bit on the third photo.

Just out of curiosity is yours a Finland or China version?
