Most consumers don't understand 4k, have no clue on HDR, and generally are ignorant. I don't think they're waiting for 4k apple tv. Although Apple's move to 4k will help a lot in this regard and help increase demand for it.
I have an xbox S for 4k right now but I still find myself switching to 1080p apple tv a lot because of better UI, airplay, and some of the apps are better. Yes, a 4k Apple tv will duplicate much of what I already have, but there's also 4k itunes store, hopefully better airplay, and hopefully better integration with iphone especially playing 4k video taken from iphone. Still need that xbox for blu ray player tho.
There's not a ton of content. 4k streaming isn't game changing (you notice HDR moreso) and you need the bandwidth. Blu ray is the biggest noticeable change but I'd guess only a small fraction are actually renting/buying 4k hdr blurays.
