Your CMF's are not the same as the standard observer. The
most practical fix is to tweak the white point on one
to visually match the other.
[ You may find after doing this that they then match at one
distance, but not from a different distance. CMF's depend on
viewing angle. ]

If you happen to know your own CMF's, then yes, you should be able to
get them to match via measurement.
