This is the answer of Florian Höch, the man behind DisplayCal, on this same matter:
https://hub.displaycal.net/forums/topic/question-about-bt-2020-3d-lut-generation/
Q: "Will generating a 3D LUT for BT.2020 be accurate when my display is limited to displaying DCI-P3? Anything higher than approximately70% saturation, depending on the color, will not be reproducible".
A: Yes. It should be of no real concern though (other than some of the patches being clipped to the same color by the display), as the profiler will figure out the limits of the display from the measurements anyway.
I think I will be ok with BT.2020 3DLUT, until something better will be implemented (P3 in BT.2020 container?). Thanks.

I don't think it's that small a niche given that relevant content and displays are all approximately DCI-P3 and not many displays have a DCI-P3 input mode so the audience is pretty much "anyone using a 3DLUT with tonemapped HDR (who isn't using a recent JVC projector)"
commentary from people who have tried this on avs says that it may be prone to posterisation errors but only you can find out whether that happens in your case and whether you notice it if it does

The real question then is why the 3DLUT creation tools don't have the ability to just make such files. It should be where this gets solved - make a 3DLUT that matches your output.
You are measuring and creating the 3DLUT in this output mode as well, aren't you? Or how do you measure a DCI-P3 LUT when your display chain is in BT.2020 mode?

yes I agree but I guess madvr added this feature because the tools aren't generally available, I haven't looked in detail but i know the relevant colourspace licence is ~£2k for example so not really feasible for the home user
my projector has a DCI-P3 mode so the problem doesn't come up for me

I hope is a viable solution, otherwise there's always the solid, even if outdated, MadVR 113b...
