Pardon my ignorance but what is crunch leather? The bags look beautiful to me.
The crunch leather has a light glazing, so it appears a bit shiny. I guess when you squish the bag, it has more of a 'crunchy' sound and feel as a result. The color dye is not even, so some parts of the bag will appear lighter and some darker. This is intentional. The leather is thinner, which makes the bag lighter.
