> Assuming you're talking about blu ray rather than dvd here too because my TV supports 4k HDR, and the last dvd player I owned was 480p.

My DVD player requires a separate input on the TV, controller, and wall socket. The player needs to be physically accessible too, and you need to store physical discs.

Changing DVDs is significantly more involved than changing a movie on Netflix, and finding something that you know you have on DVD Vs on Netflix required someone else to have correctly put the disk away.

Lastly, those things are just noisy as hell.
