I can't comment on how Peacock presents their sports in a way that causes spoilers since I don't have it. But I do watch the 4 Grand Slam tennis tournaments every year, and I hate the way those are presented when offered on a streaming service like Amazon or Eurosport. If I start up a match that shows it's only 90-110 minutes long, then I know immediately that whoever wins the first set will win the match. You can also guess which matches only go to 4 sets as well when looking at the time. Whats worse is Amazon was doing this thing where they would split the the match into part 1 and part 2 if it was over 2 hours long, so again you know immediately whether a match ends early or not.
