Considering that Netflix doesn’t have Discovery here in Canada, since the rights are owned by Bell and it streams on Crave and iTunes. And yes I can see a difference. At best, the picture quality looks as good as a DVD upconverted to 720p. And the dark scenes were very noisy with compression artifacting. I compared another show that’s on Netflix to a hard copy that I have, “Jessica Jones”. It was only issued on DVD, and the DVD looked a heck of a lot better than the garbage that Netflix was offering for 1080p.
