Some people experience this, some don't. My experience has been in between; I found that it definitely skews yellow compared to other slide films, but in a way that looks warm rather than unnatural. Downrating it to 160 or so seems to help for some people, and it may also depend on lighting. I think one person reported a "cure" based on slightly extending the first dev bath. The issue has been discussed here several times with no clear conclusion.
I thought it was known definitely to be the RSX II emulsion, and that the same emulsion was also used for the aerial film, but on reflection I'm not sure how strongly we really know that.
