Get newsletter subscribed on customer save

Question

I am trying to get the value of 'if newsletter subscribed' on customer save. I am using the event: customer_save_after_data_object for customer update and tried to get the subscription value by this piece code

protected $_subscriber;
public function __construct(
    \Magento\Newsletter\Model\Subscriber $subscriber
) {
    $this->_subscriber= $subscriber;
}
public function myUserDefinedFunction() {
    $checkSubscriber = $this->_subscriber->loadByEmail($customer->getEmail());
    $checkSubscriber->isSubscribed();
}

Though it is giving the before saved value for the subscription status. I've also tried by adding another event newsletter_subscriber_save_before, but no luck. Is there any other solution to get the desired result?

Try with below

/**
     * Subscriber factory
     *
     * @var SubscriberFactory
     */
    protected $_subscriberFactory;

public function __construct(
    ...
    \Magento\Newsletter\Model\SubscriberFactory $subscriberFactory
    ...
){
    ...
    $this->_subscriberFactory = $subscriberFactory;
    ...
}

public function myUserDefinedFunction() {
    $subscriber = $this->_subscriberFactory->create()->loadByEmail($email);
    if ($subscriber->getId(){
      echo __("This email address is already subscribed");
    }

}

[Update]

Change state of the subscription, right at the time the customer is saved from the admin end.
