No, but it doesn't need to and here's why.
Dolby Vision (DV) and HDR 10+ differ from HDR10 by constantly sending metadata to the display device based on the frame/scene. This allows the display to read the metadata and adjust the tone mapping in real time. This is a big step forward from HDR 10 which simply sends static metadata based on the entire film to tone map from.
JVC will introduce firmware at the end of October/early November for the NX/RSxxxx that introduces frame by frame tone mapping, they call it DTM (dynamic tone mapping). Meaning the projector inspects the individual frame and tone maps according to that individual frame's needs. This is actually better in a lot of ways in that it doesn't require any special encoding format (DV, HDR 10+) and works with any HDR source streamed or otherwise. It also still works with material like Disney UHD discs that lack any sort of metadata at all. This is because it's not relying on metadata, just the actual picture data of the frame itself.
About the only thing DV has to offer at this point is the potential for slightly higher color depth. Dolby has no plans to support projectors at this point and with this firmware update, I certainly don't care if they ever do.
Check out this video at around 6 minutes to see the beta of this firmware in action in Berlin using Aquaman:
You can easily see DTM adjusting the picture to exact capabilities of the projector to get the best image it can.
TLDR: DV is a proprietary encoding method that uses a data stream to tell a display how to properly display a given frame. JVC DTM inspects the actual frame data and adjusts the picture according to the frames needs
