Yes, but the limiting factor with LPCM should be bandwidth. By every account I've read, you can't ARC more than stereo LPCM because the ARC standard doesn't allow any more bandwidth. To get surround, you need DTS or DD to reduce the bandwidth enough for the additional channels. Except that I've tested it backwards and forwards and I seem to be able to ARC 5.1 LPCM through my LG C7 just fine. I don't understand how this is possible, but it seems to work. Nakamichi confirmed that it should work, but this assertion seems to contradict every other description of ARC I've read anywhere on the web. One person on the C7 thread suggested this was a fortuitous glitch specific to my devices, aided by a very short HDMI cable.
I heard from my friend that his new LG C7 TV can output dolby digital plus content which should go up to 7.1 channel.
The LG OLED's can definitely ARC DD+. And DD+ can do way more channels - up to 15 theoretically. I don't know of any sources that go beyond DD+ 5.1, but I don't do much streaming either.
Ya I believe nakamichi soundbar and creative soundbar serve 2 types of target customers. one for the better surround immersiveness and even distribbuted bass with dedicated surround speakers and dual subs, while another one is for clean convenience wife-friendly setup with simulated surround effect which can be highly affected by its listening environment and narrower sweet spot.
I think that's generally true. But I've always maintained that the 7.1 systems (new or old models) are really nice sweet spots between those extremes. A single wireless sub with two wired sats and a sleek soundbar in front is way
more wife-friendly than a full 5.1 AVR setup, but also provides surround accuracy you can't get from simulation. Yet there's very little competition in this space beyond Vizio.
And FWIW, I don't care for the "wife-friendly" descriptor very much, even though I understand it's roughly accurate for many AVS'ers. But our system is set up in our family room, and I
don't want a ton of speakers and gear piled up any more than my wife does. We want our family room to be a spot to hang out, read, and entertain as well as watch movies. I don't want it to scream "electronics geek den". I think it's sufficient to say that some soundbar systems are more "aesthetically pleasing" than other audio solutions.
