Add in the lower contrast of the colour display—the latest eInk B&W screens have a much whiter screen than the Kaleido with it's colour filter layers and a contrast ratio of ~10 or the Gallery 3 which needs to use all three colours for a "black" giving a contrast ratio of 14 (a 40% increase over the Kaleido 3 display).

The contrast percentage remains the same, only the brightness is reduced.
By using the lighting, the brightness is increased and the contrast of Carta 1200 is reached again in values.
In addition, the Boox Tab devices have a multiple screen speed compared to the Galery 3 devices and are also superior to the rest of the "Einks".
