I believe those pictures all show the same bezel, but it looks bigger on the smaller screen sizes as they probably all share roughly the same size bezel. On my 46" the bezel is quite small, and looks like the first pictures. On the 46" its 1" on top left and right and 2" on the bottom. If it stays the same size on all models you would naturally expect it to look bigger on the 40" and even bigger on the 32".
The screen is matte so its is not very reflective at all, but you will still see bright light sources in it.
As for light bleeding, I don't notice it anywhere near as bad as some pictures I've seen of light bleeding, but since its lacks any dimming its also comparable to a CCFL, so don't expect pure blacks or anything.
The bottom panel of the bezel is just like the picture of the EX720 on the Sony style site, its a dark gray, not black, but also not light gray like last years models.
