Eizo cg2730 vs cg279x

[Nicolas Hanson]

I wonder if I can save some cash by going for Eizo cg2730 instead of Eizo cg279x.

I hope to be able to trust the internal calibration, but I understand it relies on calibration with a 1D LUT only. So for 100% accuracy I would probably need external calibration with a 3D LUT that cg379x has built in. I have also picked up that I don't need the built in 3D LUT capability that comes with cg279x  if I add an external 3D LUT box (which I dont want to do) or output a 3D LUT from Resolve. 

So my question will be; what is the process of outputting a 3D LUT from Resolve when used for calibration? Is this a process done when calibrating only? If it's just a matter of doing a simple process in Resolve each time I want to calibrate, then I would probably go for the cg2730 and save some money.
