The Rec. 2020 color space used in 4K Blu-ray and high-bitrate streaming allows for richer primaries and secondaries. In , the costume design uses muted earth tones and occasional vibrant accents (a red scarf, a blue neon sign). In 4K HDR, these colors pop without appearing artificially saturated, while skin tones remain naturalistic—avoiding the "waxy" appearance common in lower-resolution upscales.

The world shifted. The motion blur of the city stabilized into terrifyingly sharp detail. Ren could see the individual fibers of a passerby’s coat, the microscopic cracks in the pavement, and then—there. In the distance, a figure moved with a fluidity that defied the lag of the city's surveillance grid.

The chase led to the roof of the Arasaka-Zeta spire. The thief stood at the edge, a briefcase of encrypted "Black Box" data handcuffed to his wrist. He turned, his face hidden behind a chrome mask that reflected the city’s lights in a dazzling, high-contrast display.

Lina, however, felt something different. When she closed the file and the hum faded, the sand in the room’s ventilation ducts seemed to shift ever so slightly, as if a microscopic wind had brushed through it. She could swear that, for a fraction of a second, a faint silhouette—an outline of the cloaked figure—flitted across the far wall, vanishing before she could turn her head fully.

When the video ended, the particles lingered for a few seconds before dissolving into a fine, glittering dust that settled onto the desk. Arun looked at his hands—his skin was still warm, and a faint, rhythmic pulse could be felt deep within his palm, matching the low hum that had filled the room.
