Answer 1

As you defined $product = $this->loadMyProduct($sku); in your code then you just need to getData of it with using attribute_code

$product = $this->loadMyProduct($sku);

// add attribute code here to get value of attribute for the product
$reservationNoData = $product->getData('whiteStore');

You can check the product attribute value.

Hope it works for you!

Answer 2

this code worked for me.

$product->getResource()->getAttributeRawValue($product->getId(), 'attribute_code', $product->getStoreId());
