Again, I think the difference between a lomo waller and a gallery work lies in the background of the photograph. Here's an excerpt from a much longer essay by Clive James.
Marketing and hype play an uncomfortably big role in today's art market and gallery scene. If that artist was among the first to confront a public used to plasticky clean HDR shots, he/she might have brought something new to the table and might be an innovator. If the photographer in question used that style because that's what galleries ask for at the moment, we might have progressed onto the second or third "I". Note that this applies regardless of effort and skill put into the actual making of the image.
PS: I like that snippet you quoted!
Trying to be the best of whatever I am, even if what I am is no good.
