Curiosity over leucistic BRBs...

So I never understood why the Rainbow Boa is called the RAINBOW Boa until I laid eyes on one. No photograph in existance can capture their beauty, I swear.

Here's my question...while researching them online, I saw a few pictures of leucistic BRBs, and I was wondering...do they have the same irridescent sheen as the normals? I can't tell by looking at photos. I'm hoping someone who has seen one in person can tell me! :)

The only thing I've been able to find was on Leucistic COLUMBIAN rainbow boas. Not Brazillian
