HLG HDR Support?

I’ve tried with the test content here:

Neither triggered HLG HDR mode on my tv with vero4k, so i found this thread…

Interestingly with the emby on the tv, only the cymatic test clip worked, the tv didn’t trigger itself for the travelxp one…

mediainfo shows for travelxp:
Color primaries : BT.2020
Transfer characteristics : HLG
Matrix coefficients : BT.2020 non-constant

and for the LG cymatic clip:
Color primaries : BT.2020
Transfer characteristics : HLG / BT.2020 (10-bit)
Matrix coefficients : BT.2020 non-constant

I’m not sure what the difference is (but I’d like to know), I’m wondering if its a bug in the TV too. I wonder if osmc can support this before LG do natively :).
