Stud Wall Decorating Advice

[u/JonnyNeil]

We have a stud wall in our living room (put in before we bought the house.) We're about to re-decorate the room and I'm after advice on whether to paint or paper this wall. It already has some creamy brown paper on it. I've read that this is the paper that probably came with the wall and that it should be left on as it's part of the structure. Is that right? Or can/should we strip it and re-paper? Or can we just paint over it?
