That's not accurate either, as the camera lens doesn't replicate an eye lens, and the positioning is critical. There are aberration and focus problems in the Rift, but it will vary by individual and how well the headset has been configured for your face. Although most people seem to say the Rift sweet spot is bigger than the Vive, it's still extremely small if you want to find the best possible image across the full diameter of the lens, and it will vary depending on your eyesight and facial structure. For instance, someone might need to have the lenses slightly higher or more tilted in order find the best clarity in the centre, at the expense of more distortion/aberration at the sides. The sweet spot for best aberration mitigation might be slightly different from the sweet spot for best focus, and so on.
And then also consider that this is a single lens, whereas your brain is combining two images from the Rift, which adds more variables, particularly if you have a very asymmetrical facial structure or different eye strength.
The video is a good illustration that the CV1 is a massive improvement in quality over DK2, assuming the images were captured using the same camera. But it doesn't represent the actual appearance of either headset. I have the two headsets here side by side, and there's no doubt that CV1 reduces screendoor and CA by a huge amount, and keeps a clarity/focus of the image across more of the lens diameter. The only major backwards step is the 'god rays', which are a permanent distraction in high contrast scenes.
