Not for apps, at least in the UK - I've had four different apps (and one in-app purchase) refunded for a variety of reasons[1] without an issue. [1] One listed features that were actually (expensive) in-app purchases, one didn't work, a new app had been released but they were still selling the old non-updated one as well (and I bought the wrong one), and one was just really clunky and borderline unusable; the in-app purchase was purchased by mistake (my thumb was resting on the home button and I hit something that triggered a purchase in the app by mistake, so it went straight through TouchID)
