Yuna's shows must make a huge amount of profit then. The lineup is always filled with successful/famous skaters.
And frankly, Yuna's show was not be filled with all top skaters all the time. The show had fair number of skaters each time, not so many big names like others. Yuna also always keep 2 3 spots for young Korean skaters who are not so impressive and have no effect on audience at all, just give them some chances to perform in front of a big crowd.
BUT Korean fans don't care about that, 30000 tickets of each show always sold out in hours just because of Yuna. For Korean, figure skating = Yuna, they don't really know or care about other legends, champions.
After Vancouver, Super Match X produced a big show in Korea with all top skaters ar that time (Mao, Rochette, Lysacek, Plushenko, Buttle, Lambiel, Shen/Zhao, Pang/Tong ...) except Yuna. They just got a huge lost, couldn't even sell a ticket, all of audience got invited or free ticket from Hyundai, ha.
