There’s no reason the broadcast of the UCBA couldn’t do dramatic finales in multiple angles and in slow-mo. They have a zillion micro-drones all over the battlefield. The live feed might be limited in the slow-mo stuff only because something else dramatic could happen immediately after the first dramatic thing. But the feed probably has a dozen PiP options, plus you can customize your feed to follow a certain contender, since there’s at least 4 different fights going on at the start of each match. The feed that Sydney and co. are watching (and us) is the “official” feed with curated camera angles and is what the Gail and Bluce are working from.
