This Apple TV doesn’t support 8K display output. That’s what it’s called the “Apple TV 4K.”

Gigabit Ethernet has 7x the bandwidth of a 4K UHD Blu-ray.

If an 8K Blu-ray standard were to ever exist, in what universe would it somehow 7x the bitrate to increase the pixel count by 4x? And of course that math is assuming that this new hypothetical new standard that does not exist wouldn’t use newer compression standard.

In what universe will 8K content be streamed at greater than 3x the bitrate of the average US home broadband speed? (300Mbps) 8K streamed content will almost certainly top out at 100Mbps.

The current bandwidth cost math at major CDNs for consumer use cases at that bitrate is hundreds of dollars per month, before you even pay for content.

The idea that any streamer will be bandwidth-limited by a 1Gbps network link anytime soon is absurd.

8K is dead, nobody was buying 8K tvs. There will almost certainly be under a million 8K tvs sold in the next decade. There's also absolutely no content for it while not even 4K content is mainstream.

8k blu-rays aren't and if they were, I don't think they would 4x the bandwidth... and even if they did, 4k blu-ray peaks at 150mbps (or so), so 4x would be 600mbps, which gigabit is still plenty for.

Commercial streamimg platforms are probably gonna allocate like 2mbps more for 8k streaming and call it a day.
