I remember seeing matches last season where a mini-cam would show reactions of the fans during matches, like the fans who wore the horse masks, while Rivington would remark on fans engaging in horseplay, or horsing around....Mini-cams during the TSM vs TL match, when TSM was making their stand at the nexus, and seeing fans react and go wild during the moments.
The LCK and LPL matches do actually swing to the fans during the matches when big plays are made, showing the reactions, but in LCS regions? Not so much. I'm guessing because there aren't really any big "HOLY SHIT!" moments that happen. Not to the caliber of last year's Spring Split UoL vs Fnatic clashes, UoL vs Gambit Gaming in the playoffs, or C9's Cinderella run through the gauntlet. Then again, LPL is known more for the brawls and the oh so succulent cheese coming forth. LCS has pretty much gone from having cheese in it from time to time(Keane on Gravity, Kikis on UoL), to now the copycat, no opposing interaction, "afraid to break a fingernail before 20-35 minutes" matches. Even the crowd pops appear far more subdued than that of last year.
