I think they are "Livestream" platform files (like those of ISSF Shooting)...
I have the app on my Apple TV and for the Shooting Worlds it worked very well...there was the chance to view all sessions live and ondemand (without spoilers) immediately after the end of the live feed...
I hope it's the same (and it works also on PC and other platforms) for UWW (but I never checked it out, since the finals sessions normally are available on some of the tv networks I can watch with my satellite dish...mainly TRT3 Spor from Turkey or the international feed, when I can find the keys to steal the pictures from it )...
by the way, I did find another option, the Hungarian TV...
they're going to broadcast all the champs live on their channels, in particular the semifinals and finals session are on "Duna World"...
all of their programs can be watched ondemand on their website (Wrestling Worlds are available outside HUN, so no VPN needed)...

you just have to look for "Birkozo Vilagbajnoksag" (= Wrestling Worlds), click on the title of the program and choose "Elò" (=Live) if you're watching at the time of live broadcast or "Video Inditasa" (= Video Ondemand) if you're trying to recover the program later (hoping that they make it available...this morning session for instance it's not there yet )...
