Based on the pixel structure, it's the same type of S-PVA panel used in the 40B650, Toshiba 40XV645U, and some Sony XBR models. (The RGB subpixels look like wedge shapes >>> when partially lit or rectangles ||| when fully lit.)
After a little calibration, here's how it compares to the A panel I had:
- no clouding anywhere (whew!)
- color temperature is much better out of the box
- black level might be slightly better, as letterbox bars are darker
- shadow detail is definitely better
- the drop-off in contrast ratio with viewing angle is about the same, but there isn't as much of a shift to blue
- the image looks somewhat grainy and blurry compared to the A panel, especially with HD sources
My conclusion:
Despite the advantages of the S panel, I think the A panel is the better TV, due to its sharper image. The difference is likely due to the shape of the subpixels. The A panel has subpixels that are rectangular even when partially lit, while the S panel has subpixels that are wedge-shaped >>> most of the time. In effect, the A panel has a finer matrix and so it probably has better anti-aliasing and the like.
Jarofwei indicated he (or she) was happier with an S panel than an A panel. I, however, am not happy at all, but I don't know whether I can justify another exchange, since there's really nothing wrong with this TV as far as I can tell.

Tell them its screen uniformity is terrible and get something else.
