I'd not get your hopes up too much about this refresh... I've just come back from YVR on CIVM and (as corroborated by BASource), CW has not seen the same refurbishment that the rest of the aircraft has. Still the hopeless old Rockwell Collins IFE, no mood lighting, and tatty (but admittedly clean) CW seat surrounds. Even more annoyingly, upstairs in CW I had no working at-seat power, and one of the toilets was out of order for a while.
Any clue why they would refurbish/upgrade some of the plane but not the J seats? Seems bizarre...
