My setup is a Ryzen 2700x with an Nvidia 1070ti.
I have sufficient bandwidth (200Mbps) and the video loads really fast. When I start playing the video everything seemingly runs Every five seconds there is a really minor tiny hiccup in both sound and picture. As I said, the video is already buffered up really well and these keep occurring every four seconds.
Here is a link to a 4K HDR video on YouTube as an example.
This does not happen during offline video playback.
My CPU and GPU usage are pretty high (50%) during playback.

What chipset is on your network interface? (Im thinking possibly along the line of interrupts on a cheap realtek card???) Alternatively this could be a software issue - what other software is running? – davidgo – 2019-02-23T19:25:42.690
@davidgo Not running any other software (that I know of). I'll add a screenshot of the processes from task manager (soon). The HDR works fine at 1440p. It buffers the data well in advance. My hunch is that the hiccup is a decoding issue. I read this when I did the research on my own:

It seems "it is known" that HDR on Chrome is not terribly fast and requires a fast PC. I am wondering if the bottleneck is the CPU or the GPU or something else.
I would be happy to explore your speculation. How should I test?
