Last week I rented a ColorMunki Photo and used the supplied software to calibrate my monitor and papers.  This question pertains to the monitor profiles it generated.

-Using graphing software such as Gamutvision and DocBee's ProfileManager I noticed that the monitor's gamut extended all the way to the bottom just like the reference sRGB.  Now I know that my LCD does not have perfect blacks.  Does that mean that the sRGB color space has a limited contrast ratio that my monitor covers?

-Where if anywhere can I read the contrast of my profiles?  I'm suspecting that this was not encoded by the ColorMunki Photo software.

-Soft proofs of papers in Photoshop with "simulate paper color" checked are way too washed out (black point raised too high).  Is this the result of inaccurate / nonexistent encoding of the black point of the monitor profile?

-Assuming the answer to the above questions confirm my suspicions, what alternative software should I use to produce a proper monitor profile for accurate paper soft-proofing?  I'm looking at dispcalGUI for Argyll CMS, is that going to do a better job?

Could be how the graphing software is mapping. See: http://www.colorwiki.com/wiki/Color_Management_Myths_26-28#Myth_26

...that seems to be more concerned with printer profile.  I am getting graphs for printer profiles whose black points are far from reaching the bottom, which is to be expected.  It is the display profile that seems to be incorrect.
