While it may be correct that the spectral distributions of the
phosphors used in CRTs cannot make a true D50 or D65, surely the purpose
of that "calibration" is to "emulate" those color temperatures to our
visual perception.

We should refrain from referring to D50 and
D65 when it comes to monitors
because it is impossible to calibrate them to
either one. D50 and D65 are
illuminants and have a specific spectral
power distribution associated
with them. A monitor does not have the
ability to produce such spectra.
We can say that we are trying to get a
correlated color temperature of
xxxxK.
