I don't know about that last bit, go to Walmart and they have most everything new and current on Blu-Ray. Plus the less-compressed video beats the pants off of streaming.
Tons and tons of Movies and TV shows are streaming-only releases nowadays.
Also, a bunch of old movies get restored in HD and released on streaming services only. First example that comes to mind is the classic 1993 comedy Look Who's Talking Now.
Adding insult to injury, a bunch of old movies get remastered physical releases... on DVD only. That's right. SD content encoded with a 30 year old codec.
So if I want to watch a movie from my childhood in HD, more often than not my only legal course of action is to subscribe to a streaming service.
In terms of things that appear in theaters. I don't expect to see Netflix exclusives on the aisles.
And the market for discs isn't what it used to be. The long tail seems nonexistent now, it's a shame old remasters aren't coming through it any more. The last one I bought was the Star Trek TNG remaster, which was on blu-ray (and looked fantastic)
Can't say Blu-Ray won with a resounding success neither… possibly because of Sony patents.
DVDs were still heavily used as compared to Blu-Ray, because people buying Blue-Rays were mostly people who had a PlayStation that could read them.
And a few years later, streaming services probably pushed the idea of buying a movie on a physical media a bit out of the window anyway.
