In relation to this lawsuit it's mostly the same, but in general it's way different. The iOS is not a gaming platform. While gaming consoles are purely for entertainment and mostly optional in almost everyone's life, phones are not. The iOS walled garden is a lot more like a Windows or Mac walled garden would be, if it existed, which would be horrible.
Phones are somehow not accepted as a general purpose personal computing platform, while they clearly are. I don't think Epic Games could reasonably sell that argument in their position, but it doesn't mean they are wrong.
