No, it would not.  The negotiation is assumed to let servers decide between
a color and monochrome version if _both_ are supplied by the content
author.  This mechanism does not require servers to do the conversion
themselves.

Part of the reason for having this header is that automatic dithering is so
hard to do.  It allows content authors to draw a separate monochrome version
for monochrome users, instead of having their color versions dithered (into
something horrible) automatically at the browser side.
