I believe the oem supplied hardware/software to control what gets written to the e-ink screen would play a factor in how fast it draws and perhaps how many shades are shown. It would be easy to blank the screen completely before generating the next page, but it would be much faster to only alter the e-ink pixels that are different between pages. I'm sure e-ink is not 100% reliable so the drawing algorithm will have to compensate for ghosting. I would think less ghosting would make things a little clearer.
