From what I've gathered this has as much to do with for the Xbox One and PS4 the discs are only "installers" these days (and sometimes worse, just "activation tokens"), and for various reasons both the Xbox One and the PS4 have some very interesting heuristics of what they bother to pull from the disc versus what they just grab from the internet. The Blu-Ray discs on those consoles are slower than people tend to think they are and I get the impression a lot of times the consoles this generation themselves just think it is faster to fetch everything from the internet than to bother trying to pull it from the drive.
