No, I'm not sure, but I don't think anyone knows to what extent, if any, gorillas, chimps etc understand or interpret what they might see on a TV screen. I know they understand mirrors as a reflection of themselves though, so maybe they do understand what they see.
Re boredom. The restful, relaxed face of most apes mirrors the 'boredom face' in humans because they have less muscles in their faces. I can't speak for Gorillas, but I have seen Chimpanzees in the wild, sitting on a jungle path wearing exactly the same 'bored' expression as visitors comment on with zoo chimps 'oh, the poor thing's so bored.....' Yet these were wild chmps totally in tune with their enviroment.
I believe that unnatural behaviours in captivity such as hair plucking, eating faeces, regurgitating(which may not be unnatural anyway) are caused by stress, unsuitable conditions,or cagemates, or inadequate diet- but not necessarily by the state of boredom-i.e. not being stimulated/wanting something 'to do'
