I think this missing part of this whole discussion is that there are two modes
in soft-proofing and they have different results.

From you first post I gather you have grayscale images with GG2.2 embedded
profiles.  If you just one the file it doesn't look how you'd like it, but if you
soft-proof in DD20 suddenly it looks correct and matches the prints that you get.
Is this a correct assessment of the situation?

If so, the soft-proofing you are doing is not what people are used to.  Soft-proof
can be set up to CONVERT to the output profile which is just like printing with
the ICC profile.  If you did this with GG2.2 to DD20 you would see identical
screens.  If the screen changes (probably gets lighter) then you have set up the
soft-proof to ASSIGN the output profile rather than convert.   This switch is called
"Preserve Color Numbers" (PCN).  PCN=on means assign-to-profile because you
are not changing the numbers in the file.  PCN=off means convert-to-profile
so that the new changed values give the same luminosity (L-value).   It's really
worthwhile playing with the Proof Setup, PCN and Preview to see the differences.

What I suspect is you have soft-proof with PCN=on and you are viewing the 
file as if it were assigned to DD20.  If so you can just Edit > Assign Profile to 
DD20 and get what you want.  

I'm not sure of your printing workflow.   If you print with say Epson ABW and have
No Color Management selected this Assign to DD20 should have no effect.  But
if you use ICC profiles in printing I'd have to know specifically what you are doing.
