There's different methods of displaying images on e-ink. As far as I understand, before displaying an image, eDGe show fullscreen white\fullscreen black pixels several times in a row, to remove ghosting from the screen. It's slow. But with the small video, they can compare two images (current and next), and redraw only pixels which were changed. Also as far as I see from e-ink site, eDGe e-ink display (by itself) CAN support 16 greyscale, but it's somehow limited (probably by display driver).
Someone with good english, send a question to Joe Kralowetz (the one from EE who responsible for e-ink display driver)
