I really don't think that has anything to do with flat design whatever that means. Apple is all about hiding non-essential information and functionality. Always has been. This is a consistent pattern you will be able to find in all their software if you pay a little attention. Basically, if Apple thinks something is a power user feature most users will not need then they have no qualms about not making it discoverable. They tend to even go a step further: they may outright hide it, making it impossible for users to ever be confused by it. I don't think that's a bad design pattern (depending on context and circumstances, obviously, as always), you just have to make the right judgement calls about what's important and has to be discoverable and what's not. This allows the software to be simple to most users while also having some depth for more advanced users. Like always in design it's all about making the right trade offs, though. The devil is in the details.
