p112  Glamo 3362 Datasheet V1.0-Full-FIC.pdf (sent copy to Joerg)

'' Dithering
When viewing image of higher color depth on lower color depth LCD
display, we tend to ignore low bits. This
causes block effect on otherwise smooth surface of the image. Glamo 3362
provides special dithering
architecture to eliminate this effect.''

But it is unclear if that is truly what goes on, there is a dithering
enable bit in a register that mentions dithering for RGB444 and RGB332
only (and the enable bit is disabled anyway).
