I guess it could be considered "self-fulfilling" in that Disney was flooding the shelves of big boxes with 3D discs despite said stores selling neither the tvs nor the players intended for them.
At least that's what did em in at Walmart.
The only "national" feeds that are 100% 4k are the DirecTV 4K channels.
And that's literally the only 4k they offer, boxes aren't supporting OTA ATSC 3.0.
Well its too late for that. Software has all but completely dried up and Disney's likely not going to do it again even if Cameron begs them to release a 3D disc that all of five people with accounts here will buy,
