Yep: YouTube currently delivers over gQUIC and h3 (IETF QUIC).
We advertise the following alt-svc for most devices:
> h3-29=":443"; ma=2592000,h3-T051=":443"; ma=2592000,h3-Q050=":443"; ma=2592000,h3-Q046=":443"; ma=2592000,h3-Q043=":443"; ma=2592000,quic=":443"; ma=2592000; v="46,43"
HTTP/3 (over IETF QUIC) is still not as widely deployed due to lesser client support, but that's growing as both Chrome[1], Firefox and Apple (in iOS Safari, when enabled) adopt it and the latest drafts.
