From some forums, we found many users have issues streaming YouTube 4K videos to Chromecast Ultra for Samsung 4K TV, for example:

“I recently purchased a Chromecast Ultra and whenever I try to cast a 4K UHD youtube video it always gives me an error message. My wireless network speed is about 400 mbps but I still cannot cast a single 4K youtube video even when I try using an ethernet cable. Factory resets do not work either. There is no issue with the actual connection to my Samsung 4K TV because I can see that the input’s resolution is “3840 x 2160/60p” . Please help!”
