Remember if we ever established at least one outbound connection to a Tor peer, including sending and receiving P2P messages. If this is true then the Tor proxy indeed works and is a proxy to the Tor network, not a misconfigured ordinary SOCKS5 proxy as -proxy or -onion. If that is the case, then we assume that connecting to an IPv4 or IPv6 address via that proxy will be done through the Tor network and a Tor exit node.
