Iridescence in Brazilian Rainbow Boas

1- do you think the iridescence in all BRBs is roughly the same, or do you think it varies?

2- if you have seen variance in BRB iridescence, do you feel it’s greater/lesser in certain color variations? For example I’ve seen a lot of color variation in normal Brazilian rainbow boas, some darker vs lighter, some more brown, orange, red or yellow.

(Forgive me if this has been discussed elsewhere. I wasn’t able to find an answer to this in my online searching.)

Generally, iridescence on BRB is more a case of ambient lighting. It improves with age/size. Darker morphs seem to show it more readily but it still shows even on Albinos. Also, some people seem better at capturing it than others. Here are pictures of the same snake under different lighting
