OK, I see.
Though use-fancy-splash-screens-p is not strictly correct on this.
If  I force it to use splash screen:

(defun use-fancy-splash-screens-p () t)

And examine these values of the splash screen on the initial startup
frame:

(window-pixel-height)
 => 476

(cdr (window-text-pixel-size
      (selected-window) nil nil nil nil t)) ; include mode-line
 => 462

it has plenty room for display.
