My question is in regards to audio processing. Do we know if these TV's will pass lossless Dolby TrueHD/Atmos from a connected source (i.e. UHD Blu Ray player, etc.) thru ARC (specifically eARC) to an external source like an AVR? I have been looking for the answer to this question, even through LG, and can't seem to get a straight answer. The 2017 OLED models got an update that allows them to ACCEPT Dolby TrueHD over HDMI but does not say if it actually do pass through (bitstream) to a connected AVR.
