(defclass my-ca-layer (ns:ca-layer)
  (:metaclass ns:+ns-object))

(objc:defmethod (#/needsDisplayForKey: #>BOOL) ((self +my-ca-layer) string)
  (if (#/isEqualToString: #@"myKey" string)
    (call-next-method string)))

Maybe the "+my-ca-layer" (with the plus sign prefix) is the trick you've been missing?
