Totally irrelevant to the discussion, which is explicitly about streaming services delivering in lower resolutions than they have available.

Streaming services already deliver in lower resolution than they available based on network conditions. Good upscaling would let you save on bandwidth and deliver content easier to people in poor network conditions. The tradeoff would be that details in the image wouldn't be exactly the same as the original - but, presumably, nobody would notice this so it would be fine.

Why would you not enhance the compressed data with a neutral network? That is where the information actually is.

Satellite data would benefit from that.
