Yes, I know, even more. I can't stress enough to people that Riot's advertisement and global support of their game is the reason LoL is such a big esport. Last year's worlds final had 14,7M concurrent viewers and over 40M unique, that is more than NBA finals, superbowl, anything but the football world cup really.
Only 1.5M or so in total was on twitch, 1M of that being on the main channel, like 5M people were watching on korean/chinese streaming sites and a ton on TV as well.
Funny cause dota2, a valve game, on this year's TI had 8 times the prize pool of League's worlds prizepool last year and yet not even 1/3rd the concurrent viewers, even less unique ones.
