It looks like the top picture has a little lightbleed in a couple of places down lower half of the long left edge. I notice you took the picture in a darkish room, as people do for these type of shots otherwise they cannot be seen.
The light bleed which I can see in the pic is a little worse than I have on my new iPad 3, I doubt mine would even show up in a pic, as I can only just about notice it even when looking carefully for it, and certainly under normal conditions it cannot be seen, and TBH even in subdued lighting i don't notice it.
AIS, I suspect that top one in the pic is borderline..it's certainly not bad, and I suspect will not be noticable under normal lighting, I also suspect the brighness is set quite high, but if it is noticable say in a room with just a wall light on, then it may be worth asking your Apple store to replace it, assuming they will do so, but only you can decide if it's worth it.
Personally, if its not visible under normal lightling conditions I probably would'nt worry about it... as I certainly would'nt say it was bad light bleed..yes it has a little, and is noticable in a darkened room, but I have seen much worse.
My wife is now using our iPad 1 which we have had for about 18-mths, and I never noticed anything wrong with it at all during that time, but a recent quick lightbleed check actually revealed it had more noticable lightbleed than my new iPad3... and yet, neither of us ever noticed it.
