The biggest technical problem is that you have no spectral calibration for
the camera. It is effectively a "colorimeter", and colorimeter instruments
work fine for characterizing displays, if you know the spectral
characteristics
of both the display and the colorimeter (all the low cost display instruments
are probably colorimeters, although they probably have a closer to XYZ
response
than most of the cameras out there.)
Profiling the camera with an IT8 is not going to help a lot I would
imagine, since the reflective target is broad band, and most displays are
narrow band sources (spectrally, the chart and the display are a very
long way apart).

I'm probably spewing copious amounts of ignorance at this problem,
so I apologize in advance.
I have found the datasheet for the sensor in my DSLR (Pentax
*ist-DS) contains the spectral response curve. I've thought about trying
to use that somehow.
As far as the IT8 being different from the CRT, that's why I was
considering generating a test chart via targen/printtarg. It looks like a
conversion from argyll's .cht format to LPROF's .ITX would be in order.
