You're right, Sony 'Camp' is BT2020:

Code:

Color primaries                          : BT.2020
Transfer characteristics                 : SMPTE ST 2084
Matrix coefficients                      : BT.2020 non-constant

It played just fine for me when I tested w/my 4K TV (which isn't HDR)

CNXSoft says:

BT.2020.20140602.ts (H.265 Rec.2020 compliant – AAC audio) – Not smooth and no audio

But, w/the Sony 'Camp' clip, I am getting smooth playback and audio (has AAC 2.0).
