I have both chromapure with d3 pro and calman with i1 pro 2.
Not sure what you are planning for a signal generator, but I use a couple of free discs in the calibration forum. One from masciola has 6.5% sized windows and I have been happy with those for color and gray scale.
Use dnice custome settings to give you a baseline. Color temp normal, gamma 2.4 for 65" and 2.6 for 55 iirc. Turn all then other BS off like NR, CATS and AGC.
I then use a 100% stimulus window to measure Y and set the contrast for my preferred footlambert result. 36-40 is fine with me. The using a test disc, in a darker room, set you brightness to the proper level.
Next is two point gray scale. I make high adjustments at 80 and low at 30. Once you get those close then you can get into 10pt gray scale and tweak them to get 20-100 flat. Avoid using green if you can, as you move red or blue up or down it will affect the other two.
Once I'm happy with that I move to 10pt gamma. With the 2.4 gamma setting it isnt hard to get a flat 2.2 or 2.25 gamma.
Color is not bad, just leave it at 50 and tint at 0 and make your adjustments in the pro menu. Chromapurenhas good instructions on how to use the color adjument module. I used the 100% saturation , 75 amplitude windows but have been told to use 75/75 so I am gonna try that innabfew days.
