Filmed with a single, hard backlight. In the standard 1080p version, the edges of the subject blur into the darkness. In the 4K Dolby Vision version, you can see the edge definition clearly. The subtle color grading shift from warm tungsten to cool LED is now visible for the first time.

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:

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.

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.
