After reading the reviews on here confirming that these cables support 4K HDR10, I ordered a set of three cables to go between various devices and LG's new 4K TV in the wall should be relocated. They work fine with regular HD devices, but when connected to an Xbox with 4K Netflix playback, they fail within a few seconds every time. It shows a few seconds of video, flickers with static or noise patterns for a second, and then turns off. Switching back to the HDMI cable that came with the Xbox works fine. All three cables have this problem, so it doesn't appear to be a single problem. The Xbox displays all of its menus and other output in 4K all the time, but the only time the cables fail is when Netflix turns on HDR10 (the TV shows a small HDR icon in the corner in this case), so I suspect it's an incompatibility related to HDR10.
