4k trial

Tried out theYTTV 4k trial, have an LG 4k HDR tv, so I thought it would be interesting....may have been except found only one live broadcast, it was a college football game...could not see any difference in picture quality at all....went to some of the free 4k scenery channels, pretty sharp pictures, but who wants to look at birds and other nature pics all day.....If you try to and watch something with 4k, you must pay for it, I wasn't going to pay for a movie that was 15-20 yrs old, when I can turn the channel and watch for free...My TV is 65" and watching thru Roku Ultra, which are all compatible with 4k...I went to need stats to see what signal I was watching, most were not 4k.......like experts say, no true 4k just an upscaled 1080p hd view, which at times are better than 4k......Glad I didn't pay for this on a monthly basis, maybe in the future it will come around??
