I don't think digital computer connections are relevant in any way. I'm not worried about the sound quality of my USB cable.
Which is where you're totally confused by the marketing BS. It's just a digital bitstream, not significantly different, with in the context of this conversation from a USB 2.0 connection. So long as all the little ones and zeros get there, the receiver will have the pertinent information to reconstruct the original source data, just like your USB connection. If it didn't reach the receiver intact, you wouldn't have any data to begin with and the result would be garbage.
