One more question, stemming from your last, HDR10-related comment:

I personally would not be chaining my horse to any HDR10 wagon yet, especially with Dolbyvision siting on the sidelines as well.
IIRC, the C2 CPU/GPU can do HDR10 decoding but not output. That is, if I understand correctly, it can play anime 10-bit material, but output in 8-bit. Is my presumption correct? If it is, then that's more than I would ask for!
I think the Anime content you are talking about is SDR 10 bit not HDR 10 bit (whether that is HDR-10, DolbyVIsion or HLG) Just like Hi10 H264 anime releases, the sources are 8 bit SDR, but the encoding is 10 bit because a view has been taken that 8->10 bit transcoding is better than 8->8 bit transcoding. Nothing to do with HDR - and the sources aren't 10 bit either...
AIUI playback of 10 bit SDR content is not exactly the same as playback of HDR-10 HDR 10 bit content. I think some metadata also needs to be carried over the HDMI connection. I don't know whether the C2 can insert the metadata. For HDR-10 I believe you need HDMI 2.0a compatibility (as the 2.0a revision added the official metadata standard - though this may just be a software/firmware tweak on some devices I don't know if that is true of the C2)
For Dolby Vision you don't need HDMI 2.0a AIUI - as they tunnel the metadata in a way that is compatible with HDMI 2.0 I believe (possibly also HDMI 1.4a)
One aspect of HDR metadata is whether it is changed on a scene-by-scene basis or whether it is fixed for the entire movie... I think scene-by-scene for HDR-10 will requires HDMI 2.1 not 2.0a, whereas Dolby Vision's tunnelling means it is already possible with existing connectivity. The downside of DolbyVision is that everything in the chain needs to have Dolby's magic dust...
(For info - The NBC/Comcast UHD Olympics opening ceremony HDR stuff was HDR-10 I believe. DolbyVision - last time I checked - was distinctly unsuited for live or as-live multicamera coverage - as used for sport, entertainment etc. TV production. HLG is designed for it.)
And after all this - what is clear is that at the moment there is very little HDR content officially available to us, there are at least three HDR standards, all of which are likely to be used by different content providers for different platforms, and AIUI Kodi has close to no support for any of them. (HLG would potentially just require a clean 10 bit path) HDR-10 and HLG are both part of ITU 2100 - HDR-10 (and Dolby Vision) both use Perceptual Quantisation, whereas HLG uses HLG. (Not sure if Dolby is part of 2100)
For those interested in HDR-10 and HLG Metadata - in this case for injection into H265 files - this is worth a look :
http://quality.tv/home SEIEdit allows injection of HDR Metadata if you've created HDR content in an NLE like Adobe Premiere, Avid Media Composer or FCP, but need to insert the correct HLG or HDR-10 metadata into a resulting file to play on a suitable player (such as the internal players in HDR TVs, or for UHD Blu-ray mastering)
AIUI Kodi isn't really aware of this stuff yet?
