Netflix streams '4K' because everyone has a '4K' TV now and they demand it. It's not inherently wrong, just practically so. The difference is that Netflix (and often other streaming services) max out at a much higher bitrate for their 4k streaming, and are using a better codec (H.265) as well. By comparison, Netflix's bitrate for 1080p is severely limited and so if you compare the two, even watching at the 1080p level of detail, streaming in 4k will often be a vastly superior experience. So it's not inherent (not a result of the resolution), but still, streaming 4k is not pointless at present.
