Did Walmart brand whole milk is real whole milk or too fresh?

I use Walmart brand to froth milk and find out it can foam very quickly with lot of foam by use same machine compare to other brand whole milk. So, I am thinking did it is real whole milk or it is little low fat milk compare to other brand. Did anyone have experience use Walmart brand whole milk froth milk? Which brand whole milk everyone use to froth milk for latte art?
