First time chicken owner confused about the gender

I just got my first chickens and I bought him a Blain's Farm& fleet. They were supposed to be 95% accurate sexed since they're sex-linked combo of golden comets and cinnamon Queens. Two are definitely cinnamon Queens two I think are golden comets, but one of the quote" golden comets has a pretty advanced comb and I'm not 100% sure if that's normal or not.

They are about 5 ish weeks old 2nd photo is the other similar one
