They replaced GIF files for many purposes, and not only do they have full
colour, they have better algorithms than GIF so may produce more compact
files. IIRC the major reason for their existence was to bypass patents
which someone threatened to enforce.

Yes, with the DCD over emulated USB that's what I would expect - it should
beat most Internet connections. You might well find no clock hopping at
all. Recall, though that usually clock hopping is NTP working to give you
the best result from a selection of similar servers. Having the Internet
servers even on minpoll=10 is a safety fallback.
Prepare for a pleasant surprise when using a hardware serial port.
