Barebones Transfers, such as many low budget BDs, lots of remastered anime - I'm too lazy to think of a specific example, but these releases are interesting in that they are, technically speaking, very good. In most cases, these films are simply scanned into HD for the sake of having a modern transfer, but see little in the way of restoration work done. They often simply have color grading performed, but will still exhibit inconsistent grain, heavy scratches, etc. Basically, the market is there for an HD release, but not big enough to warrant a full restoration.
6. Modern releases, basically anything from 2006 and up - these releases have been transferred at 2k or greater on modern telecines (spirit datacine for example) and received end-to-end digital treatment. They may have been shot on film, but once scanned, they were color graded, edited, and finished digitally. What you see on the BD is effectively what leaves the editor's workstation, NOT what comes off a film print. Technically speaking, these films are *also* limited by their scanning resolution, just as 90s films were, but worse yet, so much of their production has been done in the digital realm, from color grading to set extensions and such. It would be difficult to restore these to higher resolutions in the future, but the industry has been working with 4k for a while now, so we should be safe on that end.
