So, I'm on my third MBP, first one had an icky screen, second one had a bad screen too, and fan noise. This one seems to be great so far, except for the fact that when I'm displaying a white screen (only time I notice it is on white/really light colored screen), the lower area has some darker areas in it. It looks great on a darker color and is unnoticeable unless the screen is a uniform light color. It's just like dark streaks on either side, and seems to mostly go away if I change my angle of view. Is this anything to be concerned about? It does bug me a little bit as it seems to catch my eye, but it only seems to happen on light colored screens, such as when surfing the web. I'm not sure if I'm just nitpicking or not, considering the laptop is only a week old.  I should say that it seems to mostly go away after the screen is on for a while, leaving only a little un-evenness to be noticed.
