why, when building muscle, does it seem like a body part with tattoos is smaller or less defined?

Question

I have a sleeve on my left arm and have always just known “Tattoos= looks smaller and less defined” and I’ve never really questioned it until now.

Answer 1

I also have a sleeve on my left, but not my right. My left only looks smaller and less defined because it’s not my dominant arm. It’s always been weaker, especially since I broke it.
