Just read some comments on the HDMI 2.1 article - and as I thought most people think the proprietary 'tunnelling' approach that Dolby Vision uses over HDMI (which means it can be carried over HDMI 1.4b connections in some cases) mean that Dynamic metadata should be possible before HDMI 2.1 with DV. However if you look at the diagrams you need a lot of Dolby magic dust at every stage. (and a licence for each element no doubt...) I'm assuming some of that dust handles the tunnelling of metadata...
