Possible, but unlikely for most networks.

As a practical matter, if they're using the answer for a security baseline,
they're doing it wrong - they should be planning that based on the assumption
that their traffic *will* ride the rails of the commodity Internet (due to
outages or whatever).
Similarly, if they're looking at it for performance/latency, they need to
fix their assumptions - your direct peering can be slow and congested, while
there's actually a longer but faster path through someplace else....
