Will Certainty kill unwanted Kentucky Bluegrass without hurting Perennial Ryegrass?

I sprayed entire back yard with Roundup to kill the hodgepodge of grass and weeds that were present. I'm certain that somehow, the Kentucky Blluegrass has returned! I have already reseeded with Perennial Ryegrass. I am sick about this. HELP PLEASE


Certainty Herbicide is not for use on cool season turf like Kentucky Bluegrass and Ryegrass, it is only labeled for use on warm season turf.  Unfortunately the only option to remove Kentucky Bluegrass would be to spot treat with a glyphosate or other non selective herbicide and then reseed the treated areas 2 weeks after the last application.
