YES!  You inadvertently answered that question; in checking the Konica data
from Konica (not in the three books that disagree)  Konica is NOT sensitive
to light within about the 500-640 range, which eliminates green/yellow
green/yellow which are in the 500-600 nm range.  Therefore the 15 filter
would be equivalent, no, even if it passes yellow??
