Newbie question - am I getting Rovi data?

I bought a used lifetime Roamio OTA three days ago. I also own an S3 and in the past couple of weeks have had the pleasure of having the guide data move from Tribune to Rovi :-). How do I confirm that I'm getting Rovi data on the Roamio. My gut feeling is I'm getting it, since my guide extends to early October. On the S3 it clearly listed the provider at the bottom of the guide screen. Unless I'm missing something obvious I don't see anything equivalent on the Roamio - where do I look?

I'm running software version 20.6.1a.RC10-USA-6-846. RC, to me, means a "release candidate" - not quite a production release - hence the question. Is this the latest for the 500GB Roamio OTA?

Thanks,

Russell
