It is just that the hardware decoders on the new GPUs are good enough you don't need the CPU to do much.

Edit:
Most of the players do use CPU optimizations, they switch between paths based on supported instruction sets and will use AVX2 if the CPU supports it. AVX512 has limited utility and use in this context. But none of that matters for madVR, DXVA2 copyback can handle anything hard (HEVC 8/10 bit) and any new CPU is great for everything else. AVX2 is universally supported anyway.
