Does Gracenote contain info about past tv airings?

I'm trying to fill gaps in thetvdb database regarding "Curse of Oak Island:Digging Deeper". Trakt listed this show incorrectly as "Special" while in fact these are separate airings of extended episodes from main series and on Philo and on Channels guide it was listed as separate show. I didnt have Channels subscription for all the time so I couldn't record all of it, I know that episodes run after main show but not sure if this was true every week. Is it possible to find this information somehow?

Check out Zap2It which uses the same Gracenote data as Channels. There is actually plenty wrong with what they show for some reason (like they have a copy instead of a corrected live version), but as far as I know looks correct for the show you mentioned:
