Does a 100% white-edge score prove the whole product background is pure white?

What our actual test measured

On October 9–10, 2026, we generated a 1254 × 1254 headphone packshot through a local Itemlume candidate using a project-owned demonstration reference. The original had a near-white, paper-like background. The website’s twelve-pixel edge sample reported 10.7% pure white. After its near-white correction, 657,642 pixels were changed and the sampled edge reported 100.0% pure white.

The downloaded corrected PNG still showed near-white texture in the closed area inside the headband. We therefore did not mark the entire background as strictly pure white. This is one actual local test, not a production-wide success rate, a customer result or evidence that a marketplace accepted the image.

Name the region behind each metric

Do not turn every near-white pixel into white to manufacture a passing number. That can erase white product surfaces, reflections or useful edge information. A product/background mask needs its own accuracy review.

Use a scoped approval statement

A truthful record for this test says: outer sampled band passed after correction; closed headband background still needs review; product identity and destination rules checked separately. For your own image, identify all holes and enclosed spaces before approving a strict background. A higher percentage alone does not tell you whether the correction damaged the merchandise.

Itemlume’s tested correction was not a complete semantic cutout. The general lesson is to describe what a metric measured and inspect what it omitted. A marketplace or customer may have different background requirements; follow the actual destination rather than treating this case as a universal rule.
