Totally agree, my 10-year-old Samsung has a better picture quality. What I have noticed is that Sky channels' images are far worse than those of other streaming apps like Netflix, BBC or others.
I expected great things from the Sky Glass TV and its service, but I feel very let down. The Sky support staff are not great either, recommending you visit the community forums for help.
My only conclusion is that SKY's streaming servers are of poor quality or bandwidth, and before you say you don't have enough bandwidth, I'm on a glass fibre 1 GB connection.
