I suppose it all depends on how much time and effort was spent in post-processing D800 images. So, as long as sufficient time is spent in post-processing, and the model finally looks good, there won't be any complaints. But woe to the photogragher who spends insufficient time, or simply doesn't have the skills himself or doesn't have the money to hire someone to do the post-processing for him so that the model will look good. That photographer will be shunned by all the models. Models are people. People talk.
