Petr Kavka Chief vs. Pink/Clear Acid wash w/ Green splash Chief

What exactly is the difference between the Petr Kavka Chief and the Pink/Clear Acid Wash w/ Green Splash Chief? I mean, the two obvious ones that I see are that the green is lighter on the petr kavka chief, and that the splash is in the gap on the Pink/Clear Acid wash w/green splash chief instead of in the cup.

I ordered the Pink/Clear Acid wash w/green splash chief thinking it was a petr kavka chief, and while I still like the colorway, I was kind of disappointed to find out that it wasn’t. My other question is, if CLYW is going to make two colorways that are unbelievably similar, why can’t they just make more of the highly wanted one?
