Once we realised that it was a simple case of either using a DCI-P3 profile in the TV or adjusting the EDID Dolby block to BT.2020 which is my preference. It turned out that the Sony EDID we were using at the time had primaries very close to DCI-P3 and using a standard HDR profile with BT.2020 pushed the colours out leading to a so-called Red Push. This is something we found in the early days of the LLDV hack, before the Dolby block was decoded. But if they don't match then you will get a colour push. What's interesting is that the primaries in the Dolby block for different TVs vary quite considerably and you'd obviously expect that to match the colour profile the TV uses for DV. The difference here though is that because my TV isn't DV, I change the colour primaries in the Dolby block in the EDID to BT.2020, set TMaxPQ (Dolby max luminance) to 1000 nits and use the TV in it's standard HDR10 mode. Click to expand.I'm not seeing any colour push, although the saturation using VS10 is more pronounced vs the HDR10 version and my personal preference is the VS10 version output as LLDV.
