Unlikely to be Sky3 (to be rebranded Pick TV in 4 weeks) since this is a showcase channel for Sky on free viewing platforms and tends to air daytime tat.
Sky bought the Living group of channels (Living TV, Bravo, Challenge and Virgin1 [rebranded Channel One]) from Virgin Media last June and decided to consolidate the similar content from these and the Sky channels into a few rebranded channels.
e.g.
Any HBO content will appear on Sky Atlantic.
Channel One and Living (along with similar "type" content currently found on Sky1) should appear on Sky Living.
