That just looks like the label. The first batch labels were slightly large and they can catch on the battery door or edges. It doesn't look like there is anything wrong with your battery. I don't see any bulging and remember that the label is not part of the battery itself. The batteries are manufactured and then a big sticker is folded all around them. The seams are at the edges and can lift up. From your pictures, although grainy, I don't think you have anything at all to worry about.
