I mean... its still doing a round trip over the internet, right? Maybe I just have a very different definition of "ultra-low-latency".

Everything is relative and everything is a tradeoff, so I think what they are trying to say with ultra-low latency is that they have tried to minimise possible sources of latency and that make all possible trade-offs to favour lower latency.

A streaming music service might for instance buffer audio (which incurs latency) to get reliability, which FarPlay probably doesn't do

Yes but.

I'm looking right now at a mtr (traceroute) screen from a rural fibre-to-the-premises broadband connection in Lancashire, north-west UK, achieving 2.5ms RTT to Manchester (the nearest major city, ~60km) and 8.5ms RTT to London (~325km). Things are improving.

That's only ~10x and ~8x the light travel time, assuming straight lines which is best case. ~8.3x and ~5.3x respectively if you consider that light is much slower in fibre than air.
