Perhaps readers also differ when rendering paragraph background-colour as opposed to rendering an image. I wonder if some readers snap to the nearest non-mixed grey.
I have run various firmware (Astak,L-Book,Jinke), This version is from Jinke and does not allow you to set the screen 're-flash?' mode. I have noticed other images are washing
out (appear, then washout) when the text paints. Interestingly, cover images (no HTML Text), look fine.
