As ever, confusion arises with the physical format, the encoding approach and the mastering.
Discs are a digital delivery mechanism, as is downloading. The format of the encoding is a separate matter (bitrate, depth, compression, PCM, MP-3, DSD and so on). The mastering arguably has more impact than the rest put together.
Its all a moot point. Physical distribution of digital information is on its deathbed. There won't be a replacement Bluray or replacement CD, they are the end of their line.
While its dangerous to assume your own behavoir is indicative of the population at large, I have hundreds of CDs, nearly a hundred Blurays - and I haven't bought a single CD or Bluray for well over a year.
Why? because I download or stream everything.
Personally, I don't download films. Streaming, whilst it can look good, isn't generally as good as the quality available from a Bluray. I have Amazon Prime and Netflix. Some look awful, mainly standard def ones, whilst others are mixed. I had a trial of Sky Now, so thought I'd try a random film I know well to test the quality - John Carpenter's The Thing. The picture, whilst not bad, was nowhere near the quality of the Bluray. Worst of all, it was in stereo. I ended that trial instantly. Sometimes with these streaming services you can see "patches" in dark areas - I don't know whether it is because darker scenes tend to take up more bandwidth, or whether they're lowering encoding quality during dark scenes, presuming most people won't notice.
I watch a lot of films. I can tolerate streaming services for films that I don't want to pay out to own (worth watching once maybe), but I rewatch films, quite a lot. And if I really like the film, I want the quality to go with it. Maybe streaming will be much better in the future, I hope it is, as I currently have around 2,000 films.
All too often, you won't be getting the benefit of Dolby Digital 5.1, and also the film will be in the wrong ratio.
As for CDs, I don't mind downloading for hi-res stuff, but CD quality I'd rather own it. Again, streaming services are a little hit and miss. Other than the fact they don't have the choice I need, Spotify just isn't good enough for me - Tidal seems much better - I could easily live with it if my system was a couple of quality notches lower.
Maybe it's just me. I like quality. And seeing as we've had digital picture and audio in the mainstream market for over 20-30 years, there's no physical reason why we shouldn't be enjoying studio quality video and audio right now. The vinyl revival shouldn't be happening, because by now SACD should have been a standard. DVD should have been discontinued years ago, and Bluray now standard. How are we supposed to advance picture and sound quality when the majority of people are still watching a highly compressed, 20 year old DVD format, and listening to CDs that have been around for over 30 years?
