Maybe.

"The speed increases might happen because users of IPv6 don't have to share
an IPv4 address with other subscribers using Network Address Translation, a
technique that makes the network work harder. But Facebook's Saab isn't
ready to break out the confetti just yet.

"We're still trying to clarify the data," Saab said.
This is consistent both with people with IPv6 having faster networks and
with IPv6 being faster than IPv4 on dual-stack devices. Only the latter
would motivate the recommendation in this draft.
