I'm not a fan of the hipster Instagram thing, but it does seem to argue that there's an audience for aesthetics other than "oversharpened and oversaturated". Like most cultural norms, the oversaturated flowers and sunsets seem to create a certain amount of backlash. So I think there's hope in the broadest aesthetic sense, though how many of those people will come to appreciate the specific characteristics of *film*, as opposed to lo-fi digital capture, is anybody's guess.
Commercial work distorts our sense of people's aesthetics, I think. Bright colors and flash and bling capture people's attention and sell products, so they're kind of self-reinforcing. There's an exactly analogous problem in music, where mainstream popular music has gotten more and more "compressed" in volume and "scooped" in frequency, both of which are good attention-grabbers on the radio but terrible for longer-term attentive listening. But I'm not sure that either case really represents What People Like, so much as What Works To Move Money Around.
