I have personally seen the issue with streaming from a Samsung cell phone and the Disney+ app to a Google chrome cast and a regular not-smart TV.

Disney should hire some proper developers and QA team.
RFC 1123 instructed developers to make sure your products handled multi-homed servers properly and dealing with one of the addresses being unreachable is part of that. It’s not like the app can’t attempt to a stream from the IPv6 address and if there is no response in 200ms start a parallel attempt from the IPv4 address. If the IPv6 stream succeeds drop the IPv4 stream Happy Eyeballs is just a specific case of multi-homed servers.
QA should have test scenarios where the app has a dual stack network and the servers are silently untraceable over one then the other transport. It isn’t hard to do. Dealing with broken networks is something every application should do.
