Banal is just banal and I don't think it's got anything to do with the medium or self-awareness. Some people do it with little P&S digital things, some people do it with large format; the difference is that galleries ignore the former group because they're proles. At most, I think there is just a lazy reaction against the ultra-dramatic imagery that seems to be a greater part of contemporary photography/art - go see the "top" listings on sometime.

I have some very unkind things to say about gearheads* who seek "the best" despite having not any artistic use for it. Without reference to any particular photographer, I think that LF colour is a natural destination for technology- & resolution-fetishists and as a format, it's therefore unduly burdened with such people.

* I think I can say this because I sort-of was one and still have to try very hard not to be. The perils of being an engineer before getting into photography.
