Not to discount any of the great work Arve or Manni have done, but there's really nothing "special" about what they've done in relation to JVC (well Arve's work is definitely specific to JVC). If you go back, it all started with Manni doing calibrations vs the HDR10 workflow in Calman, but using a multiplier to make the measurements meaningful. That workflow applies to any projector with multipoint gamma calibration capabilities, assuming the controls have enough range. Dave Harper essentially did the same thing on the Epson LS10000.
Arve's tool though, is really only useful for JVC, because it's built specifically for the JVC autocal interface.
Back to general HDR calibration, it's not that different from SDR calibration, provided you have a calibration suite with an HDR workflow. Basically you just calibrate grayscale like normal, but you have to know/accept that you're going to have to deviate from the curve at the high end, and pay special attention to that when you do it.
My first HDR calibration on my RS600 was by hand with Calman, and it worked very well. It wasn't really that different from Arve's tool, which is "just" much faster and more granular.
