In the first pic I would have picked the left one to be caputo based on the color of the dough, but Now I see that it is just the lighting. Based on the 2nd pic, I'd say the right is the caputo based on the look and fermentation. But there could be several reasonings to why one dough would ferment just a bit quicker. Slightly diff amounts of yeast, one flour being slightly weaker than the other, gluten strength based on hydration and mixing, one ball being closer to the ice source in the cooler, etc.
