For a long time I have bought the digital versions of movies off of iTunes and have more recently been expanding my physical collection. I’m curious, how big is the difference between the 4K digital version of a movie compared to the actual 4K disc? If I own the 4K digital version of a movie is there any reason to also pick up the disc version?
Well Apple generally streams at the highest quality available assuming you tweaked your settings. Any upgrades are rolled in to ensure the possibility of the best quality image/sound. One the features I really enjoy.
