Is Dell Premium Technical Support Available on XPS Desktops? at Time of Purchase?

I have been using Dell Premium Technical Support (paid service contract) on an Inspiron laptop for a number of years. Availability is via phone 24/7 depending on the situation, the technician may take remote control to diagnose an issue or to assist with some other activity. 

Thinking about an XPS desktop to replace an older desktop. I would like to have the same service as described above if available. 

Dell.com offers Pro Support and Pro Support Plus (for a fee). Have read the service descriptions, but not able to determine if these services offer the same coverage as my Inspiron laptop Premium Technical Support. 

Thanks in advance,
