[dm-crypt] dm-crypt vs Luks: What’s the difference on disk

I was wondering why a plain dm-crypt partition looks like random data  
while with a Luks partition an attacker will know that the partition  
is encrypted. What is exactly the difference on disk? Is it the header  
that would tell someone thats an encrypted partition? Would a Luks  
partition with a detached header change this situation?
