People in North Korea are probably well aware about the hard truth. And also, in my opinion, it's very difficunt to create a good foreign made documentary/educational movie, which is not a propaganda itself, and is not insulting or misinformative in some way (even unintentionally). So, it makes sense to simply share the good things the North Koreans don't have access to. It's a small improvent to their life, but it's an improvement, and it makes them happier. One of the defectors said that she never smiled in NK. They should live better, that's the objective, I think. And the persuasive power of such seemingly meaningless things is very high, actually.
