In what way is it unlike any other service? It’s not the first studio specific one, it’s not the cheapest one, it’s not the largest one, it’s not the first with Disney content (and it won’t be the only one). It’s a streaming service with content that’s been on other services that will be rotated with some original content tossed in, the same as all the others.
It is not a big industry change, it’s a major player in the industry reacting to a big industry change. That’s still a big deal but the service is not a revolutionary concept. It’s Disney trying to do what others (including themselves) already do.
