Screen Filter is no substitute for a proper brightness adjust. A proper brightness adjust lowers backlight intensity, thereby making the blacks be blacker and the whites be grayer. Screen Filter makes the whites be grayer but doesn't make the blacks be blacker, because instead of changing the hardware backlight brightness, it just darkens the pixels in software.
I wonder, though, if there might not be some clever way of doing what Screen Filter does and using the API for changing the backlight within an app on the transparent window that (I think) Screen Filter uses to darken the screen. Hmm. That would allow the same outcome as SuperDim without the need for root.
(Or one could just do what one can to support the EFF proposal for a rooting exception to the DMCA for all devices, not just for phones, and then we could legally root, and all would be easy.)
