Most movies and tv shows are available for similar prices on blue rays, often in 4k versions.

While the resolution may be higher on streaming, the bitrate is often significantly worse. Beyond that Netflix has done upscaling in the past with middling success.

I’ve noticed that a lot of newer releases, particularly TV shows, are not getting Blu-ray releases.
