Maybe I’ve just watched too many cartoons, but I find it a little hard to maintain my immersion (?) while watching the show when new characters are introduced and they’re very clearly voiced by Azula, The Green Lantern, Lex Luthor, and Optimus Prime.
The characters you listed are performed by actors primarily known for voice work,. If anything, actors like Seth Rogen or Steven Yeun would take me out of it more (they don’t though, the cast is mostly excellent).
