The iPhone had a lot of prehistory in Apple, from Newton to iPod. Apple Silicon alo has a long history, starting with the humble beginnings as the Apple A4 in 2010, which relied on Samsung's Hummingbird for the CPU and PowerVR for the GPU (plus they acquired PA Semi in 2008).
So both are not very good examples, because they build up experience over long periods.

They are examples of something they could similarly do for the Apple Neural Engine but in a bigger scale in the future. They have experience deploying it in a smaller scale/different versions, they would just have to apply it in bigger scale in order to be able to compete with NVIDIA.
