I have set the image in admin for category Id: 358:

Below is the output of print_r($categoryObj->getData());

Try to use this below code in your controller. It maybe helpful for you :

protected $categoryFactory


public function __construct(
 .....
 MagentoCatalogModelCategoryFactory $categoryFactory
 .....
)
 .....
 $this->categoryFactory = $categoryFactory;
 .....


public function execute()

 $selectedCatId = $this->getRequest()->getParam('subCatId');
 $categoryObj = $this->categoryFactory->create()->load($selectedCatId);
 echo $categoryObj->getImageUrl();

Output :

Try this:

 protected $_storeManager;

 public function __construct(
 MagentoStoreModelStoreManagerInterface $storeManager,
 $data = []
 ) 
 $this->_storeManager = $storeManager;
 parent::__construct($data);
 

 $categoryFactory = $objectManager->create('MagentoCatalogModelResourceModelCategoryCollectionFactory');
 $categories = $categoryFactory->create() 
 ->addAttributeToSelect('*')
 ->setStore($this->_storeManager->getStore()); //categories from current store will be fetched

 foreach ($categories as $category)
 print_r($category->getImageUrl());
 
die('end');

The issue was having in Enterprise Magento. Its been fixed after reindexing.
