Doesn't that demonstrate it's NOT the DV-metadata delivery route (player-led vs TV-led) that's the issue then? It's the DV implementation on the display ? If both the Panasonic and Sony are being fed metadata via the same route - it's not the metadata route causing the visual differences?
Having said that - it looks like the comparisons may have been made in that review using the internal player apps? If that's the case then there is no HDMI route to have an issue with - as the DV data will neither be tunnelled nor carried over HDMI - it will just be decoded in the HEVC+DV decoding hardware/software in the display? So TV-led vs Player-led HDMI metadata implementations are moot?
Isn't the difference what the Sony and Panasonic displays DO with the metadata in terms of using the dynamic metadata to optimise the source video for their displays. (Though I thought Dolby were quite protective of that processing?)
I'm still not seeing where the TV-led vs Player-led metadata transport is cited as an issue?
