It looks like OVS includes the in-band flows in statistics, even though it does not include them in flow dumps. (The latter is intentional, the former is just an oversight.)
You should be able to dump the in-band flows with "ovs-appctl bridge/dump-flows", which is documented in ovs-vswitchd(8). There is a lot of detail on what flows in-band control sets up in ofproto/in-band.c.
