Scorsese employs heavy use of flashbacks, hallucinations, and shifting aspect ratios. The texture of the film is grainy, dirty, and tactile. This is crucial because a "bad" rip will crush those shadows into black blobs or turn the grain into digital noise. A good rip preserves the atmosphere. Let’s start with the resolution. 1080p (Full HD) offers 1920x1080 pixels of progressive scan image.
The disc runs at 25 to 40 Mbps. A 1080p 10bit encode from that source (usually compressed to x265/HEVC) can retain 95% of the visual information in a file size of 8GB to 15GB. Compare that to a streaming file at 3GB.
The difference? In Chapter 11, when Teddy finds Andrew Laeddis in the cave. The firelight flickering across faces, the mist on the rocks—in a streaming version, this devolves into macro-blocking (digital squares). In the BluRay 10bit version, you see the texture of the fire on the stone. While the keyword specifies video, any proper release of Shutter Island -2010- 1080p 10bit BluRay 60FPS should include the DTS-HD Master Audio 5.1 track.
