There's no reason that 10 bit 4K should be a problem at this point with the level of asm/SIMD optimisation for NEON that has been achieved in dav1d already from ARM64, which is basically everything but film grain and one other feature of the codec.
Even ARM32 is closing the gap to the ARM64 now.
There is also the GPU work in the Xbox One decoder which may well be translatable to GLES/Vulkan and Android* - though it should probably work fine for Windows on ARM with little changes, given it is UWP and DX12 code.
*There is already some GPU decoding work done in dav1d and the AOM Xbox One decoder branch may provide some pointers/reference for future work filling in the remaining gaps - though I doubt that it will dramatically affect decoding speed, probably more battery life, but that is what they would be after anyways for mobile use cases.
