Depending on what country you are in, Auro-3D, may or may not be an option. In the USA you will find 0 movies that support the format native. Not much better with Dolby Atmos, about 20-30 movies at present, but that is growing. With the 7009 you will be able to do 5.2.4 or 7.2.2. for Atmos you want two or four ceiling speakers.
Golden Ear has a page dedicated to setup for Atmos.

If I am not mistaken the Auro-3D is also a paid upgrade where Atmos is included with the receiver
