Yep, fully agree. At least BluRays still exist for now. Building a beefy NAS and collecting full BluRay disks allows us to brute force the picture quality through sheer bitrate at least. There are a number of other problems to think about as well before we even get to the encoder stage, such as many (most?) 4k movies/TV shows being mastered in 2k (aka 1080p) and then upscaled to 4k. Not to mention a lot of 2k BluRays are upscaled from 720p! It just goes on and on. As a whole, we're barely using the capabilities of true 4k in our current day. Most of this UHD/4k "quality" craze is being driven by HDR, which also has its own share of design/cultural problems. The more you dig into all this stuff the worse it gets. 4k is billed as "the last resolution we'll ever need", which IMO is probably true, but they don't tell you that the 4k discs they're selling you aren't really 4k.
