I had a hunch it had to use some sort of lossy compression.
Of course, the HDBase-T technology that DM uses doesn't have unlimited bandwidth either.? From what I've read it's limited to 10Gbps or 16Gbps, depending on which generation of the chipset is being used.? It sounds like 16Gbps may allow for uncompressed 4K60 4:4:4 because it doesn't have the 20% overhead that HDMI itself has, but earlier versions of HDBase-T need to use a form of lossy compression to handle 18Gbps signals.
That's good to hear, but the rest of the DM line still doesn't support it, unfortunately.? This makes it difficult to do things like share an AppleTV 4K with multiple rooms if 1 or more has a Dolby Vision capable display.

I don't have any experience with the NVX line, and am unlikely to use it in my system.? I've wondered what the NVX solutions do to video quality - whether it truly maintains original quality or uses some form of (even slightly) lossy compression.

Geoff, You'd made mention of Dolby Vision...
New NVX firmware added support for it. Just thought you should know.?
