Certainly, the speed of the net has grown by leaps and bounds over the years, but companies are interested in big compromises so although I can get 4k over streaming, the quality is palpably different from that which I can get via 4K Blu Ray on my Oppo. Even though the demands are much less, the same can be said for streaming audio. I get decent results from Tidal, but Apple Music, which has no excuse for it, is still stuck at an awful bit rate.
Someone is going to show up and be the new Oppo. I doubt CDs will ever see a renaissance the way that turntables have, but I bet now that we have hit 4K Blu Ray, it's hard to conceive of TVs ever getting that much better (I know, 8k…) that it'd be a big difference.
