I am not exactly sure. You have to speak to audiophile.
But what I know is Dolby Atmos gives you better spatial awareness meaning if a airplane fly pass in the movie, you can hear sound coming from the top of your room (through speakers), earthquake (sound at bottom). Also have surround sound.
But problem is Samsung does not have Dolby Atmos and only support their own Q-symphony. And there are many apps like Netflix, Disney+ that supports Dolby Atmos and so you cannot get those sound from most Samsung Tvs.
Exactly, what’s up with “Atmos enabled” feature for? To play Atmos thru tv speaker?
from what I understand as long as source like Netflix app or Amazon Firestick sends the data, and you have a Atmos soundbar/AVR, you will get Atmos sound.
Or am I wrong here? (With Arc/eArc of course)
Dolby Atmos support slapped on to TVs just means it is able to support and decode content encoded with Dolby Atmos audio. So if you fire up your relevant TV app like Netflix, Amazon, Disney+, and get to a show that supports Dolby Atmos (take for example, Mandalorian), you'll instantly see that the "Dolby Atmos" tag is displayed to your show's key content format support index. If your TV doesn't support Dolby Atmos, you probably only get a tag showing "5.1 audio" or its equivalent which just means it supports Dolby Digital Plus, the most common format used on streaming content and is a fallback for content that are encoded with Dolby Atmos so that far more devices can support surround audio formats effectively.
Of course, if you are just relying on your TVs speakers, your effective output from having a "Dolby Atmos" supported TV is just more accurate positional audio, but even then, it's really not much of an improvement.
Now, if you pipe that out to a audio system like an AVR or soundbar, you get the full feel as you've mentioned. But don't kid yourself about experiencing wonders out of Dolby Atmos content -- the audio mastering has to be exceptionally good to feel the full impact, such as those on Dolby demo clips. In actual shows and movies (with a proper sound system), the biggest uptake in audio performance is higher bitrate audio + far superior positional audio aspects. Still, the best experience is from high-res, non-lossy audio formats like Dolby True HD based Atmos content or DTS:X, both of which are only usually experienced via Blu-ray content - for now.
