Those are some pretty incredible results. For any single frame I found it hard to find a significant quality loss between the DeepFovea frame and the reference (obviously while looking at the Foveal target and trying to compare peripheral quality), but in motion there was a lot of interframe noise / aliasing / jitter.
While I'm sure they'll improve on those issues I'm currently wondering what kind of visual peripheral trade offs I'd make; if I had a demo in front of me I'd bet that I'd prefer running at higher foveal settings / fidelity with peripheral artifacts to running at lower overall settings / fidelity to avoid them.
