Even the most objective observer still observes from their own subjective point of view. A more modern example would be how American media, both fictional and "factual", is dominated by urban perspectives. Rural life is rarely depicted and heavily stereotyped, because the people who make and own the media are overwhelmingly coastal urbanites.
Contextualising art with questions like "Who, how, why" is a perfectly fine methodology for investigating the relationship between society and the media it produces, even if right now it means gay american culture wars over "representation".
