Right, DV + HLG. Credit Apple for trying to widen compatibility, but for Kodi use, if you don't have a HLG-capable display & HLG-capable media player, iPhone filmed videos won't look right. I'll try PLEX via Shield TV and see if my Vizio displays it okay as DV. Guessing no as this new DV may not be backwards compatible.

Some AMLogic devices do Rec2020 HLG->Rec2020 HDR10 conversion (it's a reasonably straightforward EOTF conversion, with no gamut conversion required) if their connected displays support HDR10 but not HLG, when you play HLG content.  (Think the S905X3 and S922X both do it in CoreElec)

I'm now using the CoreELEC Kodi v19 - Matrix Beta builds + ODROID N2, and with the iPhone12 Pro HLG DV clips I get CE Kodi saying it's outputting HLG BT.2020nc and my Panny OLED has a HDR(HLG) On Screen popup.

Yes - the AMLogic SoCs will output HLG to HLG compatible TVs, but if a TV isn't HLG compatible but has HDR10 support, the HLG content will be converted to HDR10 and output in that format.  When I was playing with EDID stuff using my HD Fury Vertex I removed HLG support from my TV's EDID and my CoreElec AMLogic device still played back HLG stuff in HDR - which surprised me - then I realised it was converting to HDR10.

Conversion of HLG EOTF to HDR10 EOTF within the same Rec 2020 gamut is a relatively straightforward exercise - usually based on a 1000nit peak luminance assumption in the HLG file to allow it to be mapped to a PQ EOT - and has almost no visual impact on the content.  (After all the Planet Earth HDR content was all mastered in HLG and converted to HDR10 for UHD Blu-ray release, and few people complain about its quality)
