Paris will actually have more live streams this season if you include Etam and H&M (12 this season, as opposed to 10 last season). When did Haider Ackermann live stream? He's my favourite designer and can't remember him ever streaming?
Kenzo, Mugler and Balenciaga have all live streamed before, so it's a shame none did this season. I definitely agree with Nymphaea that Paris prefer exclusivity, and also they don't seem to value the internet as a way to market their brands - many designers have out-of-date Facebook pages, while some don't even have websites!
