You appreciate that the contrast that is being highlighted in the paper is the missing 8 orders of magnitude? A little bit more than the OOM baseline claim of 10bps highlighted is neither here nor there.
Put a bunch of people in an empty, lacking as much as possible any details, room. Try to minimise an environmental stimulation. Have the people dress as plainly, boring as possible. Think of diddy's white parties, all white. Have people sing and dance and do stuff. Have a person just watch them. Do you think the person will find that this context is understimulating? Do you think that the "perception bandwidth" of them there is gonna fall down, or that people will have the same feeling as looking at an empty wall or some painting for several minutes? I don't think so, and if not then we have to think about where the information is coming from, who produces the processes that encode this information and how they produce them.
