Okay, but how is this "perceptual image compression" done?

It's odd that this is missing. Without it, it's not possible to analyze for biases w.r.t. the stimuli used or even the perceptual features they're adjusting.

There are a few human quality estimate corpuses out there. I know a year or two ago they were re-running the quality assessments with RED camera footage. Check out the NYU/UTexas/Waterloo labs working on SSIM, I bet you can download it.
