I have noticed the same thing.
It seems the units that will "render" (with software update) are the C15 and DSP speakers.

The units that "decode & render" are the 805v6, 818v3, 861vX, and Explorer all of which require both software & hardware updates.

And just to really confuse use, the Prime Headphone Amp decodes & renders with just a software update.

All very confusing.

818v3, DSP7200SE, F80, Roon Nucleus Titan.
