H.265 has several big advantages over H.264, including better compression, delicate image and bandwidth saving.

Waiting on everybody to upgrade to a MAG 256 maybe? :D
You also forgot to mention the disadvantages though, that the processor requirements are 10x greater... for a 25-40 percent decrease in required bitrate for similar picture quality.
That said, right now the limitation is hardware.
The new AVOV N set top box supports it.
I plan to broadcast some test streams in h265 later this month when I finally get around to picking up new AVOV box.
Right now though, from what I've heard x86 is taking a while to adapt, so you may not see it widespread any time soon.
If you have a fast internet connection, there is really no benefit.
We will really only see that benefit when 4k sources become more apparent.
I suppose the other benefit is smaller filesize which will make storage easier for us home theatre people. But right now the cost of storage is cheaper than the processing needed for 4k h265
As stoke said, the hardware requirements are fucking insane. Now intel quicksync can do it at better levels than software h265, according to MSU analytics, but the problem with that is the server farms that iptv providers use are xeon workstations, which do not have an integrated GPU. It would require a massive influx of cash for the providers to change everything over to h265 and it is not worth it. You would be changing a 10-14 core xeon for 3-4 i7 7700 systems, to be able to handle the same amount of streams in h265 as you can in h264. So if they have dual processor systems (20-28 cores), then you have to replace that with twice the amount of machines as you would for a single processor. Your power requirements become obscene, and your costs have just doubled again!
But you'll say, what about NVENC? NVENC is limited to 2 streams for retail cards, and unlimited streams for workstation graphics. And the quality of NVENC is crap when it comes to h265. It doesn't even support b frames, let alone 10bit (Pascal does) like kabylake does. So could you fill a system with 4 1050 cards to get 2 streams per card? No, as the hardware limitation is per machine. You can buy quadros and get past the 2 session limitation, but who the fuck is going to spend that amount of money on 4 quadros? https://devtalk.nvidia.com/default/topic/800942/session-count-limitation-for-nvenc-no-maxwell-gpus-with-2-nevenc-sessions-/
