But Xun, to me this raises a question. If you had to raise the black point
did you then wind up being slightly out of calibration? In other words, was
the black point setting originally where the calibration software said it
needed to be?

Never mind I see what I did wrong. All I had to do is to raise the black
point a bit to get all the shadow details.

Thanks that works!
I did some some further testing and comparison, and noticed that with
ArgyllCMS I still get less shadow details than the profile created using
X-rite's OEM software(ICC v2). Using photoshop's curve tool, the lowest
discernible shadow details using x-rite profile is 2. With ArgyllCMS profile
it's 4. I don't see any noticeable color casts in the shadows by either
profile.
I also get less gamut volume with the ArgyllCMS: 1,114,180 vs 1,087.920
Below is the DispcalGUI screenshot for the settings I used, please let me
know if there're anything I haven't optimized. Because I would really love
to use ArgyllCMS for my main calibration tool for its powerful features and
flexibilty. But for now the x-rite OEM software seems to give superior
result yet taking a fraction of the time.

I also ran "Very Profile", I'm not entirely sure but it also seems to agree
that the x-rite profile is oeverall slightly more accurate?

Any help and inputs are greatly appreciated!

Yes, you can use the existing ColorMunki data to create a new profile from
it. (using the commandline tools, give the existing .ti3 as last argument to
colprof. Or if you use dispcalGUI, set the desired profile type, then in the
"Options" menu -> "Create profile from measurement data...", then select the
.ti3 file)
