. . . 

I agree with everything Clayton said.

I wish people who say that good profiles correct or reduce 
metamerism would suggest how.   Three possibilities come to mind:

1.  They don't know what metamerism is and are confusing it with a 
color cast.

2.  They just don't SEE metamerism.   Some people just aren't 
sensitive to subtle shifts in color.    My wife doesn't see 
metamerisms unless they are really blatant like the ones they have 
in some science museums (Boston Museum of Science has/had a good 
metamerism exhibit).    On the other hand, my wife is a musician and 
she can hear defects in other musicians' playing that are blissfully 
UNapparent to me, a non-musician.

3.  They haven't tested it.

4.  Profilers really DO fix it through some mechanism I can't 
imagine.  If so, would someone please suggest such a mechanism?
