Yes, that's true. It seems that it is about the iris coloration rather than the pupil itself as to what coloration they appear to be. I also understand that The actual color of the eyes in animals with less melanin is yellow, but it appears as blue or grey because of light being reflected back by collagen. Collagen inside the iris scatters and absorbs all colors apart from blue or grey, which bounce back through the top layer of the iris.

It's very interesting, because I have noticed irises side by side in certain snake morphs that basically "appear" to be not much different than another specimen's irises, yet display quite different "looking" pupils. Hard to know just what exactly is going on in each case, but light wave reflection, refraction and absorbsion is quite an interesting natural phenomenon.
