Hah, why not.. We already created perceptually correct audio CODECs. Doing the same for real-time image generation seems like a worthy research area for sure!

True. And it's being done already! Here are just a few papers by my graduate school cohort.

Pdiff ("perceptual diff") uses perceptual metrics including visual acuity to diff two images. This is frequently used for image based regression testing of websites. It's really handy when you need to diff images that don't come out pixel identical every time, like images made with different browsers, or images that involve some randomness.
