What happens shooting lenses with UV/IR in place on M9??

Hi, I am just curious what happens if you are shooting lenses having UV/IR filters in place already on an M9 which doesn't require any of these filters?

This is in Leica's FAQ sheet for the M9.

The longer focal lengths, 35mm and up. Won't have any effect with a 486 filter.

With the wider lenses you may see colour shifting at the corners.

I use both the M8 and M9. Can I leave the UV/IR filters on the lenses?
For focal lengths of 35mm and longer, yes. For focal lengths wider than 35mm this is not
recommended, because through the UV/IR filter a color shift will appear in the corners.
