I found my ps4 does a much better job of upscsaling DVDs than my Panasonic blu ray player
i still buy things I really want on blu ray, not so much as I used to, but not only do streaming services sometimes remove TV shows, and films, it happened recently where even if you bought that show, you couldn't watch it any more
and it's still nice to know I can watch a film without it juddering if the internet is playing up or goes down all together
