I assume you are building a proofer profile and are going to simulate
ISOcoated_v2. Right?
If the proofer is already inklimted by the RIP you could use 400
building the profile. The simulation profile (ISOcoat...) has nothing
to do with it.

If your proofing you use relative or absolute colorimetric conversion
from simulation to proofer space. Then, -s or -S options does not
apply. However, if you plan to print RGB files without simulation you
should choose the RGB space of your files.

Then, I would kick-in black earlier like 0.1 and use some more black.
