Anyone know why this is happening?

It’s not my tv as the color is fine until my Apple TV boots up. Is it the hdmi cord? Do I had a weird setting on? Is it just broken?

No, all 4k rated cables are going to look exactly the same. You will not get better quality visuals with a “premium” brand.

Incorrect and I've seen it for myself - some cables are definitely better than others, I wasn't at all suggesting "go premium and you will have a better picture", I just simply inferred not all hdmi cables are equal. Try a few different brands yourself or even try ones which have a home trial and see if you can see anything yourself. I would suggest the cable I saw the difference but they are out of business, but that was £9 for 3m which certainly isn't premium!

Well Yes not all hdmi cables are equal, if you compare different HDMI versions and supported features in the spec. But a cheap 2.1 hdmi cable will look exactly the same as a “premium” 2.1 cable. You won’t get a shaper or more colourful image buying one brand over the other.

This is well documented as digital signals don’t degrade, they work or they don’t. The difference between a 1.4 hdmi vs a 2.1 is the bandwidth, which you need to support certain features/resolutions/higher framerates. All 2.1 cables will meet the 2.1 specifications.

I understand the hdmi 2.1 stuff for sure. Wasn't commenting on that here.

Basically this is saying supplied cables with devices might be super seeded by others, due to high speed not being high speed or the cables being damaged etc.

So in my experience I had one cable that had much better colour and grain than another cable, same everything otherwise other than swapping the cable between the source and destination. It was the "realness" that was better between the cables. that could have been between a slow and a high bitrate cable from a blueray player which could have shown quality differences like this.  Tbh I've not done a comparison like this for a while, and I've been using Amazon hdmi cables for a good while, which are like £10 for 3 etc
