Three more images from different angles:
From the left.
From the right.
From the front but a little bit lower.
I've got a new 13" MBA with a LG panel and I criticize the weak contrast (perhaps the colors are to bright; the colors don't look as strong as on my old MBP or my current iPhone 4; it could be described as a "washed out contrast") and the bad viewing angles (colors become yellowish).
In case of your side-by-side picture of a Lion I can't decide wether it's Samsung or LG. The left one seems to be more low-contrast (could be my LG panel), but the right one looks unnaturally yellowish (which could be my LG panel, too).
In case of your third post with the 3 pictures, I would definitely say that the right MBA has got a LG panel, because it's more yellowish from the side on the first picture than the left MBA is on the second picture. Plus, the right MBA on the third picture has got more yellowish colors, too.
Can you please solve the puzzle?
