I would be rather cautious of these PJ's if you are shooting for DCI/P3.
From my research it seems they are rather finicky in the way they create their color, and therefore dont play nice with the cheaper colorimeters (~$10,000 and less)
You are going to need a radiospectrometer, And the one from X-R ite is junk from what I heard, so is the 700 series from minolta. that leaves teh 800 series and above, which range in around $20,000....
That is, unless you happen to have a friendly neighboorhood Color calibration dude with all the right tools ;-)
I don't happen to have one locally, so soo much for that :-(
