As far as I am aware, no features are disabled. While I've got the S6 Edge Plus, both it and the Note 5 share the same internals.
Now on the update front. With carriers expect any updates to come around 6 months after Google announces them. For the most part, all the big four carriers are roughly on the same time lines when it comes to updates.
Additionally, compared to the overall numbers of Android and iOS users, Windows phones are nothing. They don't focus updates on low selling phones. But, if no updates have been announced by Microsoft for a Nokia/Lumia phone, it likely isn't going to get one.
With Android, expect to get anywhere from 1 to 5 updates per two years.
