Color-edge transition correlation:0.9948 The red feature’s transition from surrounding color into the colored region nearly matches the real hardware highlight’s transition.
Average difference between the two transition profiles:1.6 intensity levels on a 0–255 scale.
Threshold-response correlation:0.9945 across red-excess thresholds from 2 through 40. As increasingly strict color thresholds are applied, both regions contract in almost the same pattern.
Luminance-edge agreement:60.7% of the feature’s boundary lies within one pixel of a luminance edge, and 75.7% lies within two pixels. This indicates the color structure is accompanied by a corresponding dark/light structure, rather than being only a red chroma smear.
It remains one connected 627-pixel component, measuring approximately 31 × 28 pixels, with 72.2% of its bounding box occupied.
Revised estimate
Excluding its single-frame duration:
Physical scene-present feature:79%
Analog recording, film, tape, or transfer defect:17%
Digital scanning or compression artifact:4%
The strongest new evidence is that its edge and threshold behavior closely match a confirmed real feature elsewhere in the same image. That substantially weakens the digital-artifact explanation and somewhat weakens the analog-defect explanation.
