I think I saw some 4k content on Netflix, I presume they are using some
heavy compression algorithms (like regular HD content) to get it down to
something that most ISPs deliver. I think I nominally have 15 or 18Mbps
on my ATT Uverse link, it's been awhile since I looked at whatever they
are sending and the bandwidth it uses. I vaguely recall the Netflix
content was like 8Mbps for an HD stream. Whatever it is, it looks
pretty good, and I have noticed that some of the newer content looks
really good.
The streams do slow down sometimes and get snowy or quite pixelated, it
might be the Firestick gets confused or ATT is choking the stream.
Usually if I quit the show and start it again it is fine. I notice my
older AppleTV seems to choke much more often now and will do what
appears to be a soft reboot, and if it keeps acting up I have to unplug
it and do a hard reboot then it works better for a coupla weeks until it
starts choking again.

You've hit on the problem with 4K and we talk about this at work a lot.
Most cable and satellite TV providers are giving you 25-30mbit/sec
bandwidth for HD which is about the same bandwidth as an SD DVD which
was 1/3 to 1/4 the frame size.
If you go to 4K which is nearly 2x the resolution of 1080 and don't
double the data rate what are you getting? Distribution of 4K is
spotty at best.
Uncompressed 4K is something like 1500MB/s, thats one and a half
gigabytes every second, the storage requirements boggle the mind. We
sell storage systems that support over 7 petabytes mostly to support 4K.
As an aside the Japanese national broadcaster, NHK, is going to
produce the next Olympic games in uncompressed 8K. So far just the
storage has cost $3 million.

There is something called "QLED" now, I have no idea what that
technology does. OLED pictures are quite stunning in 4k. I'll probably
need some more bandwidth to stream movies in that format though
