The ATV 4k can be picky with cables. I used a six foot $6 CAD Amazonbasics cable and it worked perfectly. I tried a high-priced Belkin and it caused random sparkles during playback.
I'd be happier if they included an HDMI cable instead of the lightening cable. Then make the remote charge wirelessly either from the appletv itself or from QI standard like the iPhones do.Agree Apple TV is one of the worst devices for good HDMI cables next to the Roku so yes if you are going 4K and HDR those cheap cables are no good. You have to buy the more expensive cables or suffer random black screens or no video. However those monoprice are the best ones you can get at the cheapest.

I went with this one and am really happy with it. Nice build quality. Good price.I can’t speak for everyone’s experience but I just plugged my Apple TV 4K in with the existing hdmi lead I was using on my Apple TV 4. It cost me about £4 on amazon and 4K hdr works fine, not a single issue so far.
My advise would be try one of your existing cables as it may save you some money.
Wait. I thought Apple TV only supported 4.2.2These are a good deal: https://www.amazon.com/gp/product/B01D5H93FW/ref=ppx_yo_dt_b_asin_title_o04__o00_s00?ie=UTF8&psc=1
Work well allow me to get Chroma 4.4.4 without issue.
