We have a whole article just to answer the question of whether it's still worth buying movies on 4K Blu-ray. But it depends on you, your preferences and how important your movie library is to you.
Buying physical movies is less popular than it used to be, but movies and TV shows are often removed from streaming platforms, which will make movie lovers think twice about relying on streaming-only, since no one can take a physical movie away from you.
Also consider that 4K looks set to be the standard for the foreseeable future. The pedestrian arrival (and adoption) of 8K TVs means we don’t anticipate 8K Blu-ray players will ride in to replace their 4K equivalents any time soon.
What’s more, some of the best movies ever made are only just getting 4K Blu-rays, and with the best 4K movies continuing to take advantage of Ultra HD Blu-ray technology, 4K Ultra HD Blu-ray players and discs are still worth considering if you’re after the very best home entertainment experience.
