Worker put the wrong LED in, or it’s a defective LED

Looking at the installation video there is a white LED on the far left side which picks up some blue tinting from the plastic it’s underneath, this shows up a bit on the outer edges when it’s on alone in the startup sequence, but is strongest when the white LED is on and the amber is also on just next to it, that creates a small strong blue section between them.

You would need to build it into a cabinet I’m afraid, have the ONT there, then run ethernet to where you want the router, ideally through the walls but at least if it’s not through the walls ethernet is sturdier and cheaper to replace if damaged.
