Ya, the fadedness of the males is caused by having two barring genes.With the Legbars, the girls have a really dark, strong stripe the middle of the head, neck, and back. The boys' pattern is kind of diluted with faded rather than crisp edges, and it's lighter.
No barring in this case so they changes things.
Mahogany will darken the pattern and cream will lighten it so if one or both of those are in the mix things get more complicated.
