It is a wild guess, but the major difference between these spaces (in my
Profiles folder) is that I have Ektachrome Space locked. So I am wondering
if firstly, do locked profiles stay locked when they get embedded? If so,
that might be the problem!

Huh? A colorimetrically larger profile would cause this? um... no
Do you think that the LUT/Matrix profile differences be what might be
effecting
these results?
A few things...
As you have ColorThink, run the profile through the Profile Inspector
and let it take a comprehensive look at the structure.
One of the typical ways profiles fail to survive embedding is if they
have structural problems - these problems may not be in the original
for of the profile and they might not cause Photoshop or ColorSync to
choke but they can get messed up in embedding.
Otherwise there should be no reason why they are, in particular,
causing problems.... that is as far as I know...and there's always
new stuff to learn <g>
