You have seen the two dots so u know how big it is. If it is not noticeable from far or at least a few cms away, then, it's okie to swap. Look at the interior, exterior, hardware & etc, does the used bag still in gd condition? If it is, then swap it. Don't be bothered by other JPGs in other colors first. Since u like white, get the white jpg. Swap it.
Unless vice versa, don't swap it.
