Ownership issues of streaming or DRM-encumbered digital releases aside, it’s a shame because Blu-rays are typically so much better quality, and as a movie buff there’s no substitute. Triple the bitrate of streaming versions is not uncommon.
Anecdotally, on streaming services I find that original content (e.g. Netflix originals) are good, but licensed content is often complete crap—low bitrate, SDR, often limited to 1080p, horrible block artifacts especially in dark scenes. Given the choice between a 4K stream and a 1080p Blu-Ray, I’ll take the Blu-ray in most cases.
