True enough, but the libaom decoder isn't nearly as well optimised as dav1d at present, and even the dav1d devs seem to be completely ignoring 10 bit optimisation while they concentrate on getting 8 bit working well across at least x86 SSSE3/SSE4/AVX2, and ARM NEON SIMD targets.
I'd say that the progress so far is pretty incredible for such a young codec, decoder and encoder wise.
From what I remember it also took a while for the OpenHEVC decoder library to get optimised, and they weren't concentrating on mobile nearly as much as the AV1 groups seem to be - though the increased core counts and IPC of current ARM implementations may have influenced that focus to some degree.
