I think it's both things. Netflix, and other platforms, don't send lossless streams to you. Even at 4k. Plus, you are re-encoding it. Its like doing a VHS copy from another VHS, or creating a new JPEG image from another. Always there is a loss of quality.

Well a 1080p stream at 30 fps would be 1,5 Gbit/s -- a little outside the spec of most people's internet tubes. And 4K UHD at 30 fps would be around 5 or 6 gigabit. It helps to capture the Netflix stream uncompressed to remove the extra compression step you'd otherwise get at capture time, and modern encoders are pretty good, I don't think most people would notice on a laptop screen. On a 40+ inch 4K TV though, it can be quite noticeable

It's closer to VHS to DVD.
