Screen banding/distortion in dark videos

I just got my pixel 2 today, and I noticed that when I watch a dark video where there are some lighter sections in a black area, the lighter sections appear totally blown out/distorted.

For example, in the following video, the black curtain behind the stage has lighter sections that appear distorted on my phone. They almost look pixelated. This video looks terrible on the pixel 2:

(Note: make sure to see the video to the highest resolution)

Is this happening to anyone else, or did I just get a bad panel? If I watch that video on my Nexus 5x, it looks fine.

That's a very poorly encoded highly compressed video. There are huge artefacts clearly visible on my QHD calibrated monitor. I think you should find some newer videos to better judge the screen.

I knew it wasn't the highest quality video (although it is awesome), I was just shocked how much better it looked on my other devices. The reason I played it first was because it was at the top of my recently played list, but I should have known it wasn't a good example. Thanks for testing it on another monitor.

I can see the same kind of thing on certain scenes in the new The Last Jedi trailer, but since the quality is a lot higher, it is barely noticable. I really have to look to see it, which seems acceptable to me. https://youtu.be/Q0CbN8sfihY

If you want to check for banding, don't use a video. Use solid colours... Feel free to use the ones here: http://www.nullabletype.co.uk/static/styles/blah.html . No need to install anything, just go to them in a browser and scroll to see different colours and grey scales. If you screen isn't uniform, they'll be visible. I'd check in a dark room with various screen brightness levels.

I currently don't have any gradient ones to try with, but you can probably find some greyscale/colour gradients to play with online.
