I did look again. You should be able to create one DCI-P3 3D LUT and be able to map both BT.709 and BT.2020 content without upconverting BT.709 or using separate 3D LUTs. That is what I've been told. Also, you can create profile rules in madVR and use different SDR 3D LUTs for different sources (e.g. 2160p, BT.2020, etc.).

What else does the batch file do that would be useful?

 Thanks Warner, I have quoted in that thread but haven't heard back.

Not sure if you're speaking to me or the other post on 3dluts but from my side all I'd like to is have the batch script change source on the projector when hdr is detected in madvr. Like I said above, it does work fine outside Kodi but inside dsplayer, the script has trouble running python files. Someone has posted a fix but not sure what to do with it as they haven't made it clear if I need to copy and paste what they've posted or perhaps make modifications. 

Shame really, would be so useful to get this working  

 Try sending JAVS a PM with the link to the fix you found. 

 Thanks Warner, just done that. Hopefully I hear back
