I can't really tell from looking at your photos. Have you ever seen these white lines before? Does the display look like it's uneven or slightly bulging? If it does, then I would have Apple inspect it.

That's a much better picture, as I can see what you're referring to now. That looks like the adhesive is separating away with the display from the casing. It could be a sign of the battery is swelling slightly. Something that I would probably have Apple investigate.
