I think this is something you have to be careful of.  Remember the colour
management at work in showing the image on your display (no soft proof or
anything) is doing an identical thing.  Perfect black (image file) can't be
generated by your display.  Instead Adobe CMM is mapping the file black to
your monitor's black point, most likely with relative colormetric intent and
black point compensation (so there is no clipping).  So this is exactly the
same thing as what the printer ICC profile is doing only the printer black
is even worse.  So the point to remember is that you have been looking at
this sort of scaling all the time for years.

The scaling of luminance in XYZ makes sense.

Annoyingly, not that I know of.
