No, it's 4.433something Mc.  ;^)

Even when I do feed 3.579something Mc burst video into me telly, no TVI -
even if I'm on 80m.

Don't think I have anything that isn't */* system
(B-through-N/PAL-SECAM-NTSC).

A typical consumer telly will not reproduce chrominance properly if burst is
not very far off (~100 cycles).

RF in the vicinity might give it some grief, but it's up to the telly to deal
with fact that M/NTSC chroma is where it is.
