BTW

Dolby Digital Plus, which is what you posted on the Dolby track, is a digital audio compression scheme, Dolby Atmos is the name of a surround sound technology.
Because of limited bandwidth and lack of processing power, Atmos in home theaters is not rendered the same way as in cinemas. A spatially-coded substream is added to Dolby TrueHD or Dolby Digital Plus. This substream represents an efficient representation of the full, original object-based mix. This is not a matrix-encoded channel, but a spatially-encoded digital signal with panning metadata. Atmos in home theaters can support 24.1.10 channels, and uses the spatially-encoded object audio substream to mix the audio presentation to match the installed speaker configuration. Dolby Digital Plus offers higher quality than regular Dolby Digital, it was used for HD DVD films and currently by streaming services. Dolby atmos is object based surround, Dolby Digital plus is an enhanced form of AC3 which is a lossy 5.1 track encoding. DD+ adds additional channels, up to 20 I believe, but he's the kicker a DD+ soundtrack can be Atmos as well. Atmos metadata can be attached to the 5.1 channel signal to be mixed over the top and give ATMOS height channel sounds.
ATMOS in the home is delivered in 2 forms.
As Metadata on a Dolby TrueHD track or As Metadata on a Dolby Digital Plus soundtrack.
Hope that helps. Not sure about the THX since I am not interested in that for post work I do here.
