Reading this thread the common theme of it is Dish needs to add 4K live channels, the problem is no broadcaster (OTA or cable channel ) is offering one and there is no news that one is coming soon.
Back when HD first came out the TV manufactures we're sponsoring the HD Channels ( like the Discovery Channel ) for content so they could sell their products, they are not doing so this time, why sponsor it when 4K is on the net ( Netflix for example) for people to check out.
The future of 4K is the net I am sorry to say, if broadcasters/providers can't even get 1080P going how do we expect them to ramp up to 4K.
For a channel like ESPN to go 4K they would have to replace everything, imagine the $$$ to do so when they are laying people, losing subs and too expensive content deals.
With no real growth in TV subscribers for cable/sat. providers except for broadband, that is why the trend for 4K is going that way and with more of a on demand type service.
Let's also remember that this time around, the CE technology is ahead of the broadcast technology. 4k LCD panels are super easy and cheap to make for TV manufacturers. That is why they are basically only manufacturing them now vs HD. If you're in the market for a new TV you have to go out of you way NOT to get something 4k.
Cable/Sat have remained relatively stagnant with their cutting edge since MPEG4. Sure the boxes have gotten fancier (a lot fancier) but in the end you're getting the same MPEG4 signal to your TV via HDMI.
Cable/Sat have been more concerned with on-demand/ convenience watching and have spent most of their R&D developing this. Dish Anywhere/Direct TV/Xfinity/TWC have come leaps and bounds with their services in the past few years, and rival netflix/amazon in the software department (maybe not app platform availability though).
Now Amazon & Netflix are jumping into 4k and Cable/Sat need to catch up. Cable/Sat may only offer VOD 4k for many things, but live events are still a money maker for TV and 4k demand for these events will be key.
Over the internet, it's very difficult to deliver live 1080 reliably to
mass audiences, 4k is even more difficult.
Linear 4k on Cable/Sat doesn't need whole 24/7 channels. I will download/stream a 4k show if I care about it that much (I've put off watching many movies and shows knowing UHD was coming too). What linear 4k needs is just a few solid pipelines (like Direct TV is doing, but eventually more than just 3 channels). Here it can offer the most popular live events to audiences; Awards shows, Superbowls, Walking Deads etc. with the highest quality video compression. Direct doesn't need to broadcast AMC 24/7 in 4k (most of their movies are DVD quality as it is).
Unless a channel is nearly 24/7 4k content, carrying it in 4k 24/7 is a pointless waste of bandwidth. It will be a long time before channels approach majority 4k content, unless it's mostly live content, CNN4k anyone?

...Maybe in the future, there will be a time when I am mad that the MLS game I want to watch on CSNNE didn't get picked up in 4k by Direct TV, and got bumped for some RSN MLB game in San Diego... but I don't see this being an issue anytime soon.
Monday Night Football this year though? This HAS to be in 4k. 17 events. Planned MONTHs ahead, broadcast by the one network that we know is MOSTLY 4k?!?! (Even though I like Sunday Night Football much better

)
