THANK YOU Neil for your patience and taking the time for this detailed explanation. It certainly clears up everything now. I had opened the two XML files that I had from the successfully patched 1350T--before and after enabling JV--and compared them earlier, but somehow I missed that extra JCV entry. I must have scanned them too quickly, and that was why I thought the XML file provided no indication of JV being enabled. Anyway, your two pics detailing the exact added entries/differences helped my understanding immediately!

Apologies to dasilvarsa as I clearly misunderstood--I get it now.

Thank guys!! Can always get excellent knowledge and expertise here.
