Color banding

I noticed that when a video displays a clear cloudless sky I get a really distracting banding of the sky. Is this normal of is 4k screens?

It's actually the bitrate of the video being played.

On youtube, everything is compressed to smithereens so some artifacts are to be expected, even in 4k60 footage.

Pair that with the lower bitrates of 4k recording off phones and you'll get banding.

Once you get videos with higher bitrates you'll not notice any banding or artifacts at all.

If you check this one out you'll see its much better due to the 100mb/s bitrate, however youtube still crushes it in darker areas thanks to them reducing it to a much lesser bitrate.

In addition to the previous poster's accurate descriptiom of youtube's bad compression, do you have your display set to vivid ,mode? remember that since most content is sRGB, setting your display to vivid will inevitably result in banding as colour coordinates are purposely moved to more saturated areas on the spectrum. On my wallpaper, I can see banding in vivid mode that completely disappears in professional mode.

Thanks to both of you. I'm glad to know that even tho the screen is great it's not even showing its full potential when I stream videos. 

Also, yes I am always on professional mode. I don't seem to have any banding unless it's a video stream. It makes sense now.
