My question is, is there any difference in audiovisual playback quality between Plex playing an MKV of the UHD disc in this setup, playing the UHD disc itself, or playing an ISO of the disc using Kodi on the NVIDIA Shield TV? Conventional wisdom says no, but it's hard to say.

Projectors don't have Dolby Vision, except for very few (mine does not) so it's really HDR and Dolby Atmos and perhaps a few other parameters, the successful playback of which can depend upon the equipment. I've also wondered about things like HDR and Dolby Vision and advanced audio formats. In the theater, Plex (client) is run off of an NVIDIA Shield TV Pro. With Plex, I rip a Blu-Ray (as well as UHD Blu-Rays) using MakeMKV, and move the MKV onto an NAS, and the Plex server is run off a high-end PC on the network with original playback quality and no rendering. I really like Plex due to the convenience and portability. The home theater was professionally installed. I have a UHD Blu-Ray player, a 4K Sony projector, a high-end AVR, and top of the line HDMI cables and hardware in between everything.
