Lots of stuff to talk about with the ATV getting 4K, HDR, Dolby Vision and the 4K iTunes store content.

Someone posted the following response from Apple support:
Just received a reply from Craig Michaels from Apple (I sent an email to Eddy Cue) regarding 24p output on the new Apple TV 4K:
Thank you taking the time to reach out about Apple TV. At this time, Apple TV 4K doesn’t support this output mode.
We appreciate your interest in Apple TV 4K and will take your feedback into consideration as we plan for future enhancements.
I'd have waited the extra if wanting the greater capacity option. You'd not lose anything by waiting a bit longer
If that desperate, buy a tent and go camp outside your local Apple store
