I've never had a 40x8, but I've had 40x2's with excellent contrast, and 40x4's which are handled like two 40x2's in the same LCD module, again with excellent contrast.

Each row/column driver can only drive so many pixels, i.e. each one only has so much 'screen buffer' RAM inside. There is nothing more to it than that.
