I'm very sceptical of experiment design that relies on self-reporting. It is super-easy to get people to accept amazingly compromised compressed versions of original visual and audible information.
But what is that measuring? That we can't sense the difference? That information from our senses is lost when encoding it in our nervous system? That our conscious minds cannot introspect or report the difference? We know our conscious minds are unreliable reporters of what our subconscious is doing or deciding. On the other hand it is easy to show that the scene we think we are seeing is created in the mind. It is easy to trick a person into thinking identical shading is different, and different shading identical. What does that actually tell us about how to compress video?
I would prefer to go with physiology. If our sense organs can resolve it, and the nervous system can delivery the sensory information, the information is important, no matter what words our unreliable consciousness says.
