I think you're right, framing of the shot absolutely tells a story, but at the same time, when you can trust the veracity of the frame content at least you can say something about the real world even if you have to acknowledge there is a possibility of something just off-screen that would change your interpretation of events. Sometimes, the contents of the image betray that the real world diverges significantly from the author's intent, for example, by allowing you to deduce that what is claimed is actually impossible. So there is significant value in "real" images.
