Dominance is absolutely iron clad.
This is what makes KittyCats a fun puzzle game.
Remember a cat always has 2 eyes: the shown and the hidden.
The cats showing Brushed Steel are hiding Brushed Steel or something more recessive.
The Boardwalk blue was only thrown the one time... all the other times, the cat threw the hidden eye. Genesis Bronze is not a hider. Actually none of the other eyes you mention can hide under Brushed Steel. Remember also that a cat can have Brushed Steel in both the Shown spot AND the Hidden Spot and be Brushed Steel pure.
