dvhe.stn is DV profile 5, a single layer streaming format.  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.

That's just wrong. Only supporting single/base means that the implementation can't handle SDR compatible dual layer as found on Ultra HD Blu-ray. So the TV can't play those rips (this of course does not apply when using an external UHD BD player in which case the player handles the decoding of dual layer DV). Single layer DV is HDR-only and of course has DV metadata.

The Sony has the following decoder:

txt:
OMX.dolby.vision.dvhe.stn.decoder        video/dolby-vision

Kodi would probably have to send the DV-enabled HEVC stream to this decoder... 

I don't think there is any way to send a stream over HDMI 2.0.  You have to decode it and place it in one of the formats HDMI 2.0b can handle (HDR10 or HLG).  IIUC what Dolby does is use the LSBs of the chroma to hold the dynamic metadata.  HDMI 2.1 will allow the dynamic metadata to be sent as packets separate from the YCbCr picture data.
