I enjoy physical media and have a ton of DVD's and Blu Ray's. An uncle of mine got me into film, especially foreign films, and after he passed away my aunt gave me his collection of Criterion DVD's, probably 150 + films. I have those proudly being displayed on a shelf and will never get rid of them.
With that being said for 4K and beyond I'm going digital through Apple Movies. I never thought I would say that as I've been a die hard physical media forever guy for years but the quality, convenience, and price of digital movies on Apple Movies won me over. Apples bitrate is highest in the industry and their compression technology is probably the best. Apple is offering a peak bit rate of around 30Mb/s for movies and 40Mb/s for Apple TV + shows while Amazon Prime peaks around 15 Mb/s and about the same with Netflix which is disappointing. Disney + isn't much better, around 15 Mb/s but I've read some reports of it being a bit higher.
I just can't stomach buying the same movies on yet another physical format, I mean how many copies of Back to the Future can one own? lol. Bought it on VHS, then DVD, and finally Blu Ray. I passed on the physical 4K versions and bought them on Apple Movies in 4K for $15 during a sale. Pricing on Apple Movies, especially during sales as mentioned, is really good. I picked up the entire Lord of the Rings and Hobbit extended 4K trilogies for $50 this past Christmas. The 4k Blu Ray's would have been over $200 at the time, even $160 now on sale. I just can't do it.
The video below is a professional comparison between 4K Ultra Blu Ray vs streaming on Apple TV 4K. The results are surprisingly close. The 4K Ultra Blu Ray looks slightly better in some parts but its not very noticeable, not enough personally to sway me. For my setup I have an Apple TV 4K wired to my router with a 500Mbps internet connection and movies (plus Apple TV + shows which run at an even higher bit rate) look amazing.
