They don't dither? They should - on both upconversion and downconversion.
Dithering is completely different from re-sampling. Dithering is the
mixture of small dots of different colors to create the perception of
a third color. It is generally a separate process that is applied to
an image, most notably in print drivers or RIP software. Some screen
drivers (such as QuickTime or PDF viewer) employ dithering if they
know they're displaying on a low-bit (256 color) display.
All "standard" re-sampling methods, such as nearest neighbor,
bi-linear, and bi-cubic, do not employ dithering.
