SSIS-200 4K is frequently used as a "showcase disc" in high-end home theater forums (like AVSForum) because it contains extreme contrast scenes that torture-test OLED panels. A small faction of fans argue that 4K reveals "too much detail"—specifically, makeup edges or set construction flaws. However, the director, Tsuyoshi Zenigata, publicly supported the 4K remaster, stating:

For the casual viewer watching on a laptop or a phone, the difference will be minimal. But for the collector, the videophile, or the fan who wants to see every brushstroke of the cinematographer's art, tracking down the SSIS-200 4K disc is a pilgrimage worth taking.

The opening scene relies on bokeh (background blur). In 4K, the specular highlights in the background render as perfect circles of light. The separation between the subject and the background is so sharp that you feel a sense of physical depth (parallax) even on a flat screen.
