The low light levels are for using it in a dim/dark room. Having granularity at low levels is useful to make the text clear without being too bright and allowing your eyes to relax and not squint. Higher levels are for evening out the display if the ambient light isn't quite sufficient or is uneven. If you can still read the screen without the frontlight on then the ambient light is just right. LCDs like iPads have to use bright light to overcome ambient light, it's competition. Eink gets better with ambient light, it's complementary. People have gotten used to cranking up the brightness on LCDs just to see that the idea of turning it down for eink seems unintuitive.
