I think there is that. We have the benefit of seeing it and visualizing it and being told it by a viewing screen. The human memory is notoriously faulty and self-selective in terms of what it chooses to focus upon. To expect fictional characters to keep track of such details and minutia, especially ones that may not be significant to their specialty or duty in Starfleet, is putting a greater burden upon characters than we ourselves would employ in day to day life.
You get it. And said it better than I did.
Reality is not canon.
