As with any historically based work, it's hard to tell what's real and what's not. Some characters, like say, Jackie Hoffman's Mamacita, seem too good to be true (believe it or not, she is based on a real person!), and some moments too contrived to really be possible. The beauty of Feud: Bette and Joan is that the juiciest moments all actually happened. The two screen legends really were that petty. They actually did leak gossip about each other to the tabloids. And yes, Joan Crawford really accepted the Oscar for Best Actress when Ann Bancroft beat Bette Davis at the 1963 Academy Awards. (You can find the clip on YouTube, but I suggest waiting until the fifth episode to roll around before you Google. The payoff is worth it.)
