Please explain why there needs to be an upgrade. There's no business case. Even a full blu-ray 4k rip is only ~60ish Mbit/sec encoded as HEVC. Netflix and co have been pushing streaming bitrates down to sub 10 mbit.

4k uhd blu-ray peak bandwidth is somewhere around 150 mbps. Discs can be encoded in different codecs, but h.265 is common. Maybe you can buffer it, but a lot of players lack the memory to buffer enough to average out a longer scene with intense encoding (such as the parade with confetti in Indiana Jones and the Dial of Destiny). Maybe you can reencode, and AV1 might help a bit, but you're likely going to drop some detail in order to fit in 100 mbps ethernet.

  The only reason a disc is authored at that bitrate is to make bit perfect Blu-ray rips impracticably large. There is no visual quality reason to be that high. There is a reason Netflix’s top quality is a fraction of that bitrate and looks excellent.

    The 3 giant blobs of black on the screen disagree strongly.

      Netflix at ~10mbps average, 20mbps peak is sometimes a little insufficient, but enough to make most people happy. But it seems like ~30mbps average, 40mbps peak would be really, really good.
