To what extent are the set of intrinsics used for VP9/h265 decoding unreusable for AV1 decoding? My guess is that there is large amount of reusable intrinsics.

Intrinsics aren't used. The decoding is generally done by a fixed function hardware block.
Intrinsics must be used, how else is the hardware invoked?

Video decoders live somewhere in the general vicinity of the GPU and aren't invoked through CPU instructions. AFAIK.
