I personally don't think there is anything odd with William's face or neck in the 'Skype' image. IMO it's shot indoors, with a web cam, then streamed over web, then screen-captured on another computer/phone/tablet, then printed at A4 on a desktop printer and stuck on a wall, then filmed on a TV camera, then broadcast on air/web, then screen-captured again, zoomed, skewed, cropped and uploaded here.
For example, here's how image quality gives some bruising effects (left - poster from WW.org; right - Herald Sun).
