I checked and you are right. Not a determinable difference.
What my comment was the mycelium permeates through the beans and basically making an homogeneous mass. It doesn't do that since a close study indicates that the bean structure still shows even with a perfect fermentation, slightly but still present. However if the bean structure is predominant it indicates that fermentation is as bit underdone. Still OK but not perfect.
Sometimes I allow fermentation to continue at room temperature in a large pot to completely cover the block with white mycelium. Aging if you like.
