A point to bear in mind during all of this “4K” insanity is that IPTV and streaming services like Netflix et al are restricted by the bottleneck that is your Internet connection. True uncompressed 4K uses 6gb/s of bandwidth for 2SI and square division. There is plenty of opportunity to employ compression methods like J2K, to reduce the necessary bandwidth for true compressed 4K to 800mb/s, but even this exceeds most homeowner Internet service available bandwidth by a factor of 8 to 32.Most assuredly, as I can see the awfulness of it all on my OLED TV. It is, however, entirely wonderful to see and appreciate 4K when playing Blu-Ray movies. Even the sound is heads and shoulders above streaming. That is why it's worth it. Util they improve streaming capabilities, one can always knock it if streaming is the only metric.
All the best,
