Stain Grade Door – piece of veneer missing – how best to repair?

I have a brand new door stain grade vertical grain fir or hemlock. Any thoughts on how best to handle this damage? I am not sure if the door came like this or if it was damaged by the door installer. A replacement door is probably close to $800 after delivery. It is the bottom of the door on the room side face of the door so I am not sure anyone but me would notice.
