Brightness and contrast are two different things. I do not dispute you view that it is a visual improvement but interestingly the specs for e-ink original said the contrast was 8:1 and for the visiplex is is 7:1 so maybe the black isn't as black or something. iLiad is seen by people to be as good with the old screen so there may be more differences that we think that influences this.
