Brawley BM Cinema Camera Sample Footage Not Playable

Four of the five graded files we downloaded from John Brawley’s Palmdale Diner sample footage are HDR10, but none of them are playable using QuickTime or the IINA player for macOS, because they were mastered in DCI P3 rather than BT2020 (P3-D65 Limited).

When using the IINA player, the footage looks dreadfully dark and shadows are appallingly crushed, whereas when playing in QT, the picture flashes and the images are dim and lacking in contrast.  

We’re also told that the clips look over-saturated and dark with crushed shadows when viewed on an LG C9 OLED with a Dune Real Vision media player. You can download the graded files and see for yourself.
