Is this LHP73B normal or failed ?

Hi erveryone ! I've just received a Convoy M21B with LHP73B this evening. Unfortunately I forgot to capture this situation in my unbox video. So anyone could tell me this is a failed chip or this is because I turned on turbo for 1 minute ? The flashlight seems to work well and it's really bright despite its small form. I wonder if this is a manufacturing error or not ?

Thanks all !
