Mitsuki's Sage Transformation is a special case, he could be using Sage Transformation with Sage Mode, we don't really know with the current available information. Plus, we weren't shown a coloured version of the transformation so we don't really know what the colour of the iris is.

Dojutsu overlaps the yellow iris, as shown when Sasuke used his Sharingan with Curse Mark Transformation.
