Not positive; but I was under the impression that Amoled screens were not susceptible to screen burns because of the makeup of the screen itself. Going to do a little research to confirm this, will get back when I am sure. I have had my 820 for almost 10 months and I don't have anything close to a screen burn; but then I rarely leave my phone on one screen for any length of time. Even when screen burn was common on CRT's it took a great length of time for it too happen. But again I am not positive.
