Hello Oliver,

for grayscale images exist special gray scale profiles. You have no 
device profile selector for them to explicitely support that kind of 
conversion.

Yes, omit preceptual and saturation. In PS they are not to be found anyway 
under theyre rendering intent names (and works slightly different than 
in lcms). The only use of distinguishing them is to show the media 
whitepoint (or paper colour) on screen or to adapt to the monitor 
whitepoint.

kind regards
Kai-Uwe Behrmann
