The readable parameter formats the XML Request
correctly in debug mode but the SOAP Response is

Responses are generated by the SOAP server you access - not by SOAP::Lite.
If you really need readable responses, copy them to your favorite XML editor and run the XML formatter on them.
This produces far more "readable" output than SOAP::Lite's readable does even for requests.
