What i know from the past is for realtime guarantees ethernet does not cut it. So you might be right.

AFAIK Ethernet is used for realtime audio distribution, so that can't be completely correct.

AVB and TSN are relatively new addition to Ethernet, and specifically designed for realtime AV use. Traditional Ethernet is not really intended for tight real-time use.

There is audio distribution real-time and nuclear reactor (or avionics, medical, etc) real-time. I assume the people doing (or certifying) the latter will want better guarantees.
