If you have a undithered shallow gradient from black, it will look terrible as you can clearly see bands where the pixels go from #000000 to #010101 (or whatever color the gradient goes towards) and further steps. We had one of those gradients in an app where an image faded out to black, it looked great. And then on the next phone model, the black background was really black instead of a dither pattern and it looked absolutely terrible.
