This is the same with the GM i1 Photo profiles.  If you select Simulate
Paper Color then Simulate Ink Black is automatically and irreversibly
checked (except by unchecking Simulate Paper Color).  One can Simulate Ink
Black without simulating paper color but not the other way around.
Interestingly, the Epson provided profiles (Mac 4800 driver) don't allow you
to Simulate Ink Black at all.

We're not sure what Adobe does when you check these settings, what it looks
for etc. I know this is one area where Roy would like to know more - for
obvious reasons.

BTW on a properly calibrated display, unless either (a) your display's black
point is as weak and exactly the same as ink on the paper you are looking
at, or (b) you are not illuminating your print with the same lighting as was
done using the profile ie D50, then it is simply not possible that the two
can have the same black without checking Simulate Black Ink (when allowed).
As we have discussed many times this is not an exact science though and a
multitude of things (such as other colours in the filed of view) go into the
mix.  As I noted a day or so ago I also found the black point shift to be "a
lot" but in line with a GM generated colour profile for the same paper (ie I
gained comfort that at least QTR ICC appeared to generate the same look as a
GM profile).  I put the print vs display difference down to the very real
fact that my print viewing conditions are not D50.  In fact they are far
from it.  I have halogen ceiling lighting that is probably at best
3100Kelvin.  Hence the recent discussion on Solux bulbs.  In 3100K lighting
the prints will look considerably darker than soft proofed display.
