Apologies to members for a side-topic answer.
LG OLED, as they have
in-house made SoCs and do not rely on external companies for main features, troubleshoooting and firmware updates. Several other companies predominantly use MediaTek's TV chipsets and those can be troublesome. I have LG C9 55 and it works reliably for more than two years. Firmware updates have been coming all the time. They enabled and improved many features: LPCM 7.1 lossless pass-through, more reliable eARC, better HDR tone-mapping, WebOS, new video data blocks in EDID, etc. Commendable.
The biggest single
audio feature any new TVs need to bring finally is
native eARC output from main processor. I hope 2022 models start bringing this. This is important, as currently all internal TV apps, USB media and network-related services, such as DLNA that pick up movies/music from servers and NAS, only have ARC audio channel on the main processor and cannot output lossless audio from TV itself. eARC is a pass-through feature only, delivered by mux chip (shown below), for use with external HDMI sources. That's why Plex or any other app on TV cannot do DTHD, DTS-HD MA and lossless object-based audio.
There are workarounds, of course, such as connect network devices as external sources or directly to AVR and use Plex or other apps on Nvidia Shield, NAS, APple TV or PC, but this is not elegant, it powers on more devices and brings more potential AV glitch points into play.
Here is the problem on current TV chips.
