LG OLED can output Dolby Atmos (DD+) over ARC (so streaming Dolby Atmos format from Netflix etc.) but not TrueHD - this requires eARC, I belive.
This is what I initially believed, but I can't find anything definitive. I have therefore resolved that this will not be the deciding factor as to which OLED to go for. As long as there is a streaming box (Apple TV, Chromecast, etc) that I can connect to my AVR to do Atmos, the TV purchase will be all about the picture.
Maybe I'll email LG and all for a definitive answer, and get the answer in writing.
Saw the Panasonic FZ950 in JBs today. Maybe it was placebo, but it did look better than the EZ950 playing identical content right beside it.
