Do all D50 cameras have IR contamination and not black blacks?

I just took a look at some of my wedding pics my uncle snapped for me using my D50 and kit lens back in May 2006. Black suits look black to me, not brown/magenta. All shot in RAW, straight out of the camera. I also combed through some other RAW files from other dates, black leather coat looks black, black pea coat looks black.

Not seeing a problem with mine. My D50 was purchased brand new in late 2005 I believe.
