Springboot mongodb - how to verify object has been removed from array of objects?

Based on my previous question Springboot MongoDB delete an object from array of objects I'm able to remove an object from an array of objects in mongodb collection. Below code is working for me to remove:

String pin = httpServletRequest.getParameter("address_pin")
                        .trim();                           
Query query = new Query();
query.addCriteria(Criteria.where("customer_id")
                .is(customerId)
                .and("customer_addresses.address_india")
                .elemMatch(Criteria.where("address_pin").is(pin)));
                            
Update update = new Update();
update.pull("customer_addresses.address_india", Collections.singletonMap("address_pin", pin));
                            
UpdateResult result = mongoTemplate.updateMulti(query, update, "customer_addresses");
System.out.println("::: DELETE SUCCESS ::: " + result.wasAcknowledged());
                            
    //  FindAndModifyOptions options = FindAndModifyOptions.options();
    //  options.returnNew(true);
    //  CustomerAddress addressesAfterDelete =  mongoTemplate.findAndModify(query, update, options, CustomerAddress.class);
    //  System.out.println("::: AFTER DELETE ::: " + addressesAfterDelete.getCustomerAddresses().toString());

Here, updateMulti and findAndModify both are working fine. I can verify in Compass that the object matching with the criteria has been removed.

Is there any built-in method in UpdateResult or in FindAndModifyOptions to verify? result.wasAcknowledged() returns true even if query criteria does not meet.

How do I verify delete in mongodb was successful or not in spring-boot?
