The fabrication method seems to leave a small gap around the edge of each colour filter to let more light in but it's still a lower contrast technology than the equivalent black and white eInk pearl screen. See the attachment to this post for a picture of the filters:

I've also found that the more light there is on the screen the more uniform and white the background looks (ie all the pixels with RGB filters in front of them that are set on white). In dull conditions the filtered pixels are quite prominent in a checker board pattern - as shown in the attachment here:
