And the pixel shader math HDR -> SDR conversion should then not downconvert the gamut if there's a BT.2020 3DLUT.
Thanks, but isn't this assuming the SAME profile/calibration is used in the display for all the 3D LUTs? As I can't do this, I have to use the custom profile external command to enable the correct calibration in the display, so that I can have iris open / high lamp / filter for HDR (SDR BT 2020) and iris closed / low lamp / no filter for SDR, correct?

Great news, will be very useful for 3D and nVidia users, sorry if I missed this in the change log.

So do you have an answer to my question: how do I select the calibration in the PJ with a batch file? I don't need the JVC commands themselves, I know them, I just need to know how to send them from a batch file. A user has posted how to do it in Python in the JVC thread, but I don't know how to call a python script from a batch file.

So any information (ideally an example of a batch file sending any command to the JVC) about achieving this would be very useful.

Thanks!
