I often use my phone mostly for looking at the bus time widget. So the wallpaper and the wallpaper background of the widget does make a difference (admittedly small difference). Note that the app can be used not just for oledifying wallpapers - you can edit wallpapers on it too and crop/resize them for your different screen sizes etc. The main reason I built this was for the crisp true blacks and then from the research, I found it might make a small difference in battery life too.
