It would seem so:

(cons (face-attribute 'default :height)
      (progn
    (set-face-attribute 'default nil
                :height (- (face-attribute 'default :height) 6))
    (face-attribute 'default :height)))
=> (120 . 110)

With 'global-text-scale-adjust', in a fresh emacs -Q, I see that:

(cons (face-attribute 'default :height)
      (progn
    (global-text-scale-adjust 1)
    (face-attribute 'default :height)))
=> (120 . 130)
