The bottom two pixels on the front of the Netherite helmet glitch into the texture of the piglin's nose, and I assume this happens with other helmets as well (besides gold, since those pixels on the texture have just been removed). Since you can apply other helmets to piglins via dispenser, the pixels should be removed on the other types of helmets as well.
