Dolby content with PowerNode ?

Hi all Recently upgraded my to to a LG C3. I have PowerNode attached via hdmi earc I have pass through set on the TV And PowerNode is attached to a pair of kef ls metas However in both 4k streaming and blu ray movies, on the ‘now playing’ screen on the bluos app I get no logo for digital or Dolby Is this to be expected? A bit confused by all this. Thanks Andy
