From the specifications on eARC, the answer must be YES. But DV is already an added value that should not be ignored, so dynamic HDR is just better than static HDR
The LG media player shows an error with HD audio but I don't have eARC enabled on the TV or an eARC receiver... yet. Just wondering it anyone has done it before getting a new eARC receiver.
I've watched a few things and so far the HDR and or DV just look a little washed out on the LG 77C9.
I set my old Kuro next to the 77C9 and it’s hard to tell any difference watching the same movie. Regular Blu-ray on the Kuro and UHD 4k with HDR on the other. If I then play the regular Blu-ray on the 77C9 it looks better. As it’s contrast seem better. Maybe the OLED is not as good at HDR because of the lower brightness and the extra white elements use to get it as bright as it is muting the colors a little. Motion and sharpness is also way better on the Kuro.
