I hope Kodi V18 support Dolby Vision decoding, as of now, the Alpha version did not.

My TV can play single-file remux style files but not ISO and folder style. I know Kodi can play ISO and v18 alpha may play folder style files, and of course Kodi already support HDR. Is it copyright issue makes Kodi not support Dolby Vision?Kodi is able to play 12 bit content. So it might actually work. But there is much more to that .... the chain from content up to the TV. I really wonder how your PC alone would be able to output 12 bits precission and the 10000 nits dolby vision is able to do.
Sorry for poor English.

I question if there is a lot of value in trying to decode DV in Kodi until HDMI 2.1 is out. In the current environment, HDMI 2.0a/2.0b can only pass directly the so-called "static" metadata of HDR10 and HLG formats. HDMI 2.1 would allow passing DV, HDR10+, and SL-HD2 "dynamic" metadata. As it is, my understanding is that to fit within the HDMI 2.0 format parameters, a DV player combines the base and enhancement HEVC Main10 layers into a 12-bit Y'CbCr 4:2:2 picture, and then through some trickery encodes the metadata into the LSB of each chroma component. The resulting pictures are then sent over HDMI as RGB (4:4:4) to get around the HDMI format and bandwidth limitations.
Holding off to HDMI 2.1 should also allow for alternative color space ICtCp (constant intensity) representations. Another benefit is that it seems more aligned with ATSC 3.0 standards.
Corrections to my tech understanding welcome.

The base layer uses the same parameters as HDR10 video, but without processing the DV dynamic metadata I'm not sure how good just rendering the base layer looks.It looks much better than ordinary HDR10, I think it's brilliant and amazing.
