When will UHD become available

It' would be great have UHD available on the Sky Store app and web store.

The above is disappointing especially when others charge the same or less for UHD than Sky do for HD.

Is the lack of UHD on the App a way of Sky locking in purchasers of Movies and TVs in UHD to Sky Q subscriptions?
