I think he talks about devices that eg. have a 6+6+6 bit display, but are
displaying a standard indexed image. The palette of this image should only
contain colors that actually look different on this device.

Additionally there is need to dither without involving indexed images, eg.
when going from 8 bits per color to 6 bits per color. (This is also done
with audio.)
