I don't disagree given your "most" qualifier, but there's a case where every level of hardware would benefit: compression of textures generated at runtime, either via procgen or for e.g. environment maps.
This is in a frustrating state at the moment. CPU compression is way too slow. Some people have demoed on-the-fly GPU compression using a compute shader, but annoyingly there is (or at least was at the time) no way in the GPU APIs to `reinterpret_cast` the compute output as a compressed texture input. Meaning the whole thing had to be dragged down to CPU memory and uploaded again.
