Would the two utility meters correctly reflect the energy I consumed?

Yep, that is how 415VAC is obtained.
But is it how it's metered?

I haven't gone through the math, and I'd overlooked the fact that each
meter sees a power factor of less than one, so I can't say now whether I
think the meters would read correctly. But if there's a way of looking
at the problem that makes the answer obvious, I've yet to see it.

Do it the old fashioned way: make a test! Can't be that difficult, can
it?

Of course not. I'll just get out the 415VAC resistive load I happen to
have lying around, and see what registers.

If you can't find it, you can borrow mine... Oh, wait, too far away!
