4K Blu-rays are more complicated than they need to be

I’m a big fan of physical media, and I have multiple shelves in my house dedicated to my Blu-ray collection. In fact, I don’t have enough shelves for everything, so there are quite a few areas where I just have movies stacked on top of each other. What doesn’t help this growing problem is having to rebuy discs just to get some features that weren’t on older ones.
