They are mastered in 4K instead of 2K like many films. For example, the present release of Ghostbusters utilized a 2K master that was used for the remastered DVD release from several years ago. The new release of Ghostbusters next month will come from a new 4K master, which is equivalent to the film's native 35mm resolution. Will there more than a marginal difference between it and the original BD release? Probably not.
