OK so maybe I was a bit too optimistic considering spyder2 support in argyll is 
still in beta stage...

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...

here's the log :

Doing check measurements

  Current Brightness = 69.13
  Target 50% Level  = 15.05, Current = 14.62, error = -0.6%

The instrument can be removed from the screen.
