here's a compare of the spyder2pro software on top, and argyll at the bottom 
with the exact same settings on the CRT display :

there's a major lack of green with argyll...

It just seems like you've set different white point targets, that's all.
Otherwise the results seem of comparable precision.

You don't say explicitly what white point you are aiming for. If you
used this:

  dispcal -v -yc test

or this:

  dispcal -v -yl -p0,0,20 test

then you would be using whatever the native white point
of the display is as the target. If you want a specific
white point such as D65 (typical of video standards), then
you need to specify it:

  dispcal -v -yc -t6500 test

or for 6500 K black body:

  dispcal -v -yc -T6500 test

You need to figure out what white point your test software
is actually comparing against (Daylight 6500 ? 6500 degrees K black body ?
How is the reference being determined ?)
