I wish I was better at IDing YB but unfortunately it's a tough one for me. That definitely looks DG but I honestly don't think it has YB either, the edges of the belly of my YB DG are much more pixelated and her color is even a little more yellow. Hopefully someone better with YB can confirm because I'm not 100% Do you have pictures of the parent that supposedly has YB or siblings that for sure have YB?
