Well said. Although streaming can generally be very acceptable to most, and is sometimes even quite good, there can at time certainly be a noticeable distinction between the streaming version and the disc version. Even with 1080p content. Recently, it was most noticeable with Moana where I streamed it just to see the difference between that and the bit-for-bit blu-ray copy on my Kaleidescape system. No comparison in that instance. On the Netflix version, the colors were more muted, I'd see slight artifacting, and the soundtrack lacked the clarity and overall oomph that I was used to. Don't get me wrong, it would've certainly been good enough for most kids (and even most adults), but I've been spoiled enough to where I only want the best. That was via a 4K Apple TV for what it's worth.
My biggest problem with streaming is how VARIABLE the experience can be during a single viewing. At least where I'm at, sometimes it bounces between HD and SD, or goes from 5.1 to 2.0 stereo then back. It can really take you out of a scene. Really annoying. And sometimes your internet decides to burp and you get kicked out momentarily.
It's beyond just quality, but the overall experience to me. But no matter what, I am such a huge fan of proper 4K HDR with Atmos or DTS:X, that when it comes time for a proper movie session, I go to the disc/Kaleidescape versions 100% that it's an option.
Don't get me wrong. Streaming is fantastic for TV shows or original content, but I don't know if I will ever abandon my physical or home-stored media.
