A:Answer Short answer is, NO.
LG CX does not have DTS support and does not passthrough DTS of any kind to your receiver or soundbar.
You may always connect your source, DVD/Bluray/Console to the receiver and pass the video to the TV, but be careful with with PS5 and XBOX Series X, most of the receivers won't support advanced video functionalities such as ALLM, Freesync/G-Sync and 4K 120fps.
