Nintendo DS Backlight

[Synful Serenity]

My DS, when playing in total darkness, I can see at the sides of the screen a small amount of bleed from the backlight, like a couple small amorphous blobs of different size and shape on each edge. Is this normal, for all you DS owners, and would you consider it grounds for exchange?

I don't see any problems on mine. It wouldn't have affected me much though, I had to go check in a dark room just now, since I've always played in a lit room.
