@kota1 The article is out of date in some respects, Apple added spatial audio monitoring to Logic Pro at version 10.7.3 (current version is 10.7.5). Both Apple and Dolby user guidance describe this (on the production side, which the writer was addressing).
To be terminologically precise, you would be listening to the same mix, but a different rendering. I can’t offer an opinion on whether the spatial audio renderer is better/worse, I haven’t used Atmos via the other services. From your position, you are still faced with different playback scenarios to (potentially) try out one way or another.
