I'm curious about the 'new hardware has enabled us to' part. I know they have full control over software, hardware stacks(A,M chip, Metal, OS), so I can easily imagine they do their best to optimization.

Is it possible to do the same job with same performance on Android? or Windows or any general target OS and software stack?

Seems that shader itself does not costs too much(normal map? lookup table?). What really matters is their UI/Shader job scheduling in realtime constraints on any CPU/GPU load state.
