    Looks like it could be a source texture format issue. Unity's builtin bloom doesn't specify what sort of source texture it needs, it just assumes what its given will be the correct format of HDR - this means, if for whatever reason the texture fed into it is a very low bit depth format, the bloom's entire chain will use that format throughout the effect, possibly causing banding.

    To know for sure though, what Android device/OS/graphics API are you testing it on?
