In general I think the answer is yes.
This comes down to your intent though. Notice I said "proofing". By
proofing I mean an intent for an absolute match where the original and the
reproduction are viewed side by side, and the color assessment is
highly critical.
If your intent is perceptual (ie. you would like a pleasing image),
and particularly if the source is a different device (like RGB for
instance), then the instrument differences become much less important
given everything else going on (gamut mapping, white point adaptation,
comparing the images from memory rather than side by side etc.),
and my "extremely obvious yellow cast" becomes a "barely perceptible
yellow cast".
