Well, we could say thanks for posting the link - I should have done that yesterday, but I was only on my iPhone, which makes posting links a bit inconvenient. So I didn't bother, and since anyone can do a quick google themselves... 
I think many people don't understand these terms like "Atmos" correctly - and the Dolby website is not enlightening at first glance either. What is not explained, above all, is the fact that there can be no "Atmos" experience from normal stereo audio. Surely there are processors in the devices that can generate something like a virtual "3D" sound from any kind of audio. However, this is just eyewash (or better: earwash).
And when I look at this "Echo" speaker from Amazon, the idea of being able to experience spatial sound through it is just ridiculous. The thing is and remains mono, simply because it is only one device in one place - no matter how many internal speakers there actually are and no matter how much phase rubbish they produce to irritate human auditory perception. It's similar to the boomboxes of the past - you could only hear stereo if you pressed your nose against the flap of the cassette compartment.
The Wikipedia article does mention headphone and smartphone implementations, but only indicates that this is also just virtualisation. This has the disadvantage that it depends, for example, on the circumference of the listener's head. One of the reasons why virtual front localisation in headphones failed decades ago. At least with my thick skull...
