Fenix 7x sapphire solar, solar ring problem

Hello! I just bought a new Fenix 7x sapphire solar version and I noticed that the left side of the solar ring differs from the right in that there is a strong shade of green colour and it doesn't matter what angle or lighting the solar panel is viewed at. Only under direct sunlight falling on the solar ring does a uniform light brown tint appear. Is this a problem? The solar panel reacts normally to the sun and charges.  look at a solar ring under direct sunlight, there is no green tint, but that part looks lighter than on the opposite side.
