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.

Do you have QoS running on your TP-Link? that can lower your throughput, I wouldn't usually expect by that much but I do not know your router, and sometimes there are just bugs with some builds of OSS firmware that have given really low bandwidth for some people until they reported it and the firmware was fixed.
If QoS is off, check for newer firmware, and also try a factory reset, especially if you did not do that when you first swapped to OpenWRT.
Worker put the wrong LED in, or it's a defective LED
