The click bait title is misleading and your information about Dolby Atmos is incorrect.
Cinema-grade Atmos allows for up to 118 positional objects and 10 (9.1) bed channels (128 total). A maximum of 64 individual speakers/subs are addressable by the Atmos renderer (or 62.2).
Translated to the home version: you have up to 20 positional objects (any additional objects from the cinema files are combined with the closest adjacent objects based on their positional metadata information - Dolby calls this spatial compression), 7.1 bed channels (the stereo overhead bed channels are converted to two fixed objects), and a maximum of 34 speakers and one sub channel are addressable.
Please do better research. :)
