iCloud Data can be obtained with just a search warrant. The power of the All Writs Act is in making a company do work to assist in decrypting or accessing data, rather than just handing it over.

From Apple's Legal Process Guidelines [0]:

"It is further ordered that, to the extent that data on the Device is encrypted, Apple may provide a copy of the encrypted data to law enforcement but Apple is not required to attempt to decrypt, or otherwise enable law enforcement's attempts to access any encrypted data."
