Have you tested it? I have tested it extensively on my AMOLED 5t and it made my battery worse, and I had to deal with less than ideal screen quality in the meantime.Why? It was a neat feature for amoled users such as 6p but of course useless to others with LCD panel. The fact that some users have the 6p at around 2 and a half years now gives Smart pixels and itd burn-in protection a star in the seat. In my viewpoint its worth it especially if it gives you a little bit more longetivity for your display.
