The kernel is obviously close to vanilla Linux, but one could also define the OS as "which lower-level services and interfaces the applications see and are programmed to use" - so the stuff on top of Linux matters.
There are more interesting, general, and lower level innovations out there - sure. But the mobile OSes do have improved security from some kind of permission system, VM (only partially because native components are common), one user account per app (IIRC) and such.
