Possibly, but then you don't provide a display color profile so maybe
it's your display that's washed out, not the image.  What may happen is
that the Adobe RGB->sRGB happens just fine but what you *SEE* is the
sRGB, not what the image should be when mapped to the color profile of
the monitor.

Again, I'm mostly talking out my be-hind here.  I've done some articles
on the color management stuff so I've played with it and I have both
monitor and print profiles set up.  But I'm not completely sure where
the conversions happen on the file open and display pipeline.

Again, this seems to me to point to an incorrect monitor color

Like I said, this could be because there is nothing to ask about.  The
file is opened by converting from its original color space to the
working space and then displayed that way.  The "asking" may only happen
when you want to convert from the original color space to your display
color space (which could be your monitor profile or a print profile, for
example) before conversion to sRGB for working.

Again, this just a guess.  I'm talking enough to convince myself but we
really need someone with more color management experience explaining it.
