We held ours up to the screen at the same angle as the photo and they look the same.
Think it might just be the camera angle.
The ear on theirs is just a tad more pointy.
The ear on ours are different from each other. The one on the back side of ours is more pointy. Ours came to us mint in the box.
When these were taken out of the mold they were then filed if needed to make them smooth so would guess that they are not all exactly alike.
