madVR can do the "same" thing as a synthetic 3d LUT in real time by simply not sending meta data not using pass through. the of a benefit of HDR SDR 3D LUT is that it cost less processing power.
as always there are exception to the rule.

calibration is a complicated topic so there is no easy way.
to get a relatively brighter image you need to lower the target nits.

you need to load the 3DLUT maker shipped with dispalycal.
there the sources needs to be BT 2020 ST2084 10000 CM/m²
your tone curve "needs" to be ST 2084 (roll off)
now you come to the place where you select the "brightness" or gamma if you want to call it even through it clearly isn't gamma by setting the target peak CM/m² lower is "brighter" image try 200.

now you need to know your target (your TV gamut and stuff like this which a meter would read) i just assume BT 709 here so you need to load a synthetic BT 709 icm which can be created in displaycal directly.

the 3D LUT format needs to be madVR and convert HDR to SDR.

or you just as a reminder you let madVR do it in real time.
