How can I stop receiving beta updates in iOS 9, so that I can get out of beta updates but not revert to 8.4?

I have an iPhone 6 with iOS 9.1, and I am pretty sure that is a beta. Once 9.1 officially comes out, or if it is already out, then now, I would like to stop receiving beat updates. I do not want to downgrade my system, I just want to get official updates from this point on. On Apple's website it says you have to go into recovery mode and go to 8.4, but for what I want to do, and since iOS 9 officially came out, can I avoid doing that? Do I just have to delete the profile and that will stop it? Or will "Leaving the program" do what I need, although it only says I wouldn't be able to submit feedback and receive beta emails? Hopefully I don't have to go into recovery, and thanks you for your time.
