I have no reason to lie. I LOVE my MB, and the display is excellent. I have seen some inferior ones at the store, but mine is really great. It all depends on the manufacturer I guess...
Just curious, but have you really examined how your MB handles blacks? The test I usually do in stores is to put it on the planet earth wallpaper and look at them side-by-side to see how true colors are when messing with brightness.
I just came from the Apple Store and Best Buy because I'm shopping for one of these, and the results are pretty consistent. The MBP screens achieve a very nice contrast ratio and accurate blacks while the MB's are VERY washed out. And I've been looking around and have seen no info regarding two separate display manufacturers.
