No foveated compression is not foveated rendering. It is using the same general idea for a different area of the problem: a higher bitrate (on the wire, or across the wireless link) for in-fovea.
Due to latency, you can't render the fovea area only; you need to cover quite a bit more in case the eye moves between submitting the command buffer and the final image being ready.
Compression can happen much later in the process, where the latency is much more predictable or even fixed. This is useful because massive bandwidth is easiest along traces, harder along wires and hardest wirelessly.
