I went to comex and look at their demo set. it's flat and when you close the type cover, there is no visible gaps between the cover and the screen.
2nd thing, has anyone check for light bleeding (is this what you call them) ? mine has visible light bleeding at the top and sides (lanscape mode) which i suspect is due to the "curvature" of the screen.
This is how my curve looks like not much only the top part is curve a little... I would not called it super or too much. Sorry if yours is worse than this then you should as for a exchange.
