There are distinct differences in the HLG curve to V Log VGamut for BBC HLG Rec2020 (or 2100) interp, NHK HLG Rec2020/2100 to Vlog interp and the Rec2020 HLG to VLog Gamut colour space transform from Lattice.

NHK HLG to Vlog VGamut Output Bounds RGB: 0.125031, 0.90232 BBC to Vlog VGamut to Output Bounds: 0.125031, 0.793651 Lattice Rec2020 HLG to Vlog VGamut Output Bounds: 0.125, 0.85892

Could you explain?
