I created a ccss and an edr for JVC NX9 projector, using spectral data (provided by @KarlKlammer) that was captured via Qalif spectrometer.

The files are shared here.

JVC NX9 owners having an i1Display Pro (alone) may use the provided edr in ColourSpace to get higher accuracy in measurements as compared to the default projector edr that comes with the probe.

Other details are provided in this post on avsforum.
