Possibly — but they haven't put them on iPlayer either. They've held off until it's been broadcast.

I just checked and people watch more live TV than I expected. See bottom of page 8 here:

(iPlayer would come under Broadcaster Video On Demand — BVoD)

Bottom of page 10 is 16-34s, which probably looks more like what you'd expect.
