Comment (by heleppkes):

 Try to pass the sws flag to make it print info about the conversion
 parameters used, I don't remember the syntax off-hand .. but if it says
 that its using a "specialized" converter, then it won't execute the
 generic dithering pass. You can usually force the generic path by passing
 the accurate rounding an full internal chroma flags.
