Mostly, yes -- don't bother. It depends on the type of photgraphs. A
clear blue sky tends to filter fairly well, where a human face will
fare worse (although even then, a clear photo taken in studio
conditions can benefit from filtering).

I guess the question to ask is "what are you hoping to gain by using a
filter"? Even on a mobile platform, space is unlikely to be at a
sufficient premium that you'll get any significant benefit from doing
so. An exception to this is for computer generated images. But since
you've said you're using photographs, I'd say it's not worthwhile.
