I'd be rather surprised (read horrified) if any of the packages assume

a display is grey balanced.
It is easily verifiable. Create an RGB black to white gradient in
Photoshop, set the info palette to display RGB and LAB simultaneously,
move your cursor around. a*=0, b*=0. If yours doesn't, please send me
your display profile and let me know what created it because that's
what I'm looking for.
It defeats the purpose of profiling.
No it doesn't. Profiles contain more information that that which could
be used for determining the gray balance of a display.
I'm sure
that almost all display calibration utilities aim for a perfect gray
balance,
and that very many of the display profiling packages include a
calibration
utility. It does not follow that because a package includes a
calibration
utility that aims for a perfect gray balance, that the profiling
algorithms that
follow it, depend on this being the case.
Thank you.
