Benjamin Moore did this with their paints in the past two years, and the colors are noticeably more dull now. The SDS (safety data sheet) for some of their most popular paints like Advance used to have the specific amount of 25% Titanium Dioxide, and they now list the range of 20-25%. From reading on the internet, this compound is the white base and also is in short supply these days. So now colors like Simply White are actually pretty dull and grayer now. You'll notice this easily if you put something with the new color up against the old color, where the old color will show as the brighter one.
