The only way I can think of is to list all the names on the bus, and
when you see a well-known name, use GetNameOwner to look for the unique
name that it maps to. Basically you build your own inverse mapping
table, then see what entry or entries match the unique name you are
interested in.

This example script
<https://github.com/ldo/dbussy_examples/blob/master/list_bus_names>
may be helpful: it can list the owners of all well-known names on a
bus, using e.g.

    list_bus_names --owners session
