No-as of 10/17/2014, Premium Caller ID is only available on the following devices:
If you subscribe to Premium Caller ID and receive an incoming call from someone already in your Contacts/Address book, the name will appear as it is in your Contacts/Address book.
Yes-to block your number from displaying on the phone of the person you are calling, dial *67 + Phone Number (as you would normally dial it) and your name/number will not be displayed on that single call, regardless of whether the person you are calling has traditional Caller ID or subscribes to Premium Caller ID.
If you purchased Premium Caller ID name display but see an incoming caller's name as "Private", "Restricted", or "Unknown", then the caller's name is not registered or has set their name as "Private" in the CNAM database.
If the incoming caller's name appears as "Blocked", the incoming caller has dialed *67 before dialing your number to intentionally block the name/number from being displayed. It could also mean the user has permanently had name/number blocking set in their profile.
