Not so much. Data revenue is per byte, regardless of ipv4 or ipv6.

Bear in mind the consideration is for support of an existing service, if
we're talking terminating ipv4 services.

For new services, it's different, because you have opportunity costs and
the additional costs of supporting dual ipv4/ipv6 infrastructure.

I think the reason the discussion has moved on to mandating an ipv4
shutdown, is because the economics of dual ipv4/ipv6 infrastructure aren't
competitive, so there's the desire to simply wish away ipv4.
