This exactly. I've got all six original Star Trek films on UHD blu-rays. I was recently visiting my mother and we watched The Voyage Home (the one with the whales) streaming on her TV. The compression artifacts were immediately apparent. I won't judge color accuracy or contrast, since we have very different TV technologies. But I shouldn't be able to see mpeg blocks on a 4k stream that the provider charges extra for!
