Will Amazon accept your main image?
Main images need a pure white background (RGB 255, 255, 255), at least 1000 px on the longest side for zoom, and the product filling most of the frame.

Questions
Why does light grey fail?
Amazon expects exact white. Studio white often photographs as RGB 245–250, which can get the listing suppressed.
