This is kind of a shot in the dark.  I don't know anything about shotwell, 
and not much about darktable.  But I know darktable automatically applies
an exposure correction curve to the raw file when it imports it, and ufraw
does not (unless you set one as the default).  You might look at the 
exposure correction curve darktable applies and see what it looks like when
you apply a similar curve in ufraw.  There may be other automagic things
darktable does in regards to color; not sure.
