While looking into how to get the LightSpace exported JVC 1D LUT applied to my JVC DLA-X700R, I first found out that that's not possible with the JVC auto-cal software for my model year (2014), but then happened upon Arve's JVC Projector Tools on GitHub.
That tool was written for model year 2015 and beyond, but with a small tweak it works for my projector too. The tool is primarily intended to create HDR gamma curves, which are no use to me as the 2014 model year did not yet feature HDR (or HDMI 2.0 for that matter).
I can download the contents of the Gamma > Custom 1/2/3 > Import slot on the projector, which results in a table with 256 10bit values for each primary colour. Arve's tool saves this in JSON format to a .conf file:
256 entries each for R, G and B.
Once loaded (or generated), it can then be uploaded to the projector to one of the three gamma Import slots.
My question: can I export a 256 value LUT with my current LightSpace HTL license or would this have to be added as a special export format? I'm willing to modify Arve's tool to add an import function, but want to know first if I can even export the data from LightSpace.
This could potentially make the grayscale calibration of the Projector a lot easier. In my case in particular, as JVC only allowed 2-point calibration on my model.
