Thanks for your replies,

They sent me a replacement anyway without needing to return the original one but the replacement arrived today and its much worse than the pictures above. Every leaf is damaged and the leaves are very pale but I just got it planted anyway and have to hope for the best.

The name is Magnolia denudata Yellow River I got mixed up, I already have a pink one cant remember the name which is about 26 years old so its big and beautiful, I thought a yellow one would be a nice addition
