Let’s explain a few terms for the LG 2020 soundbar series.
2.1 = front left/right and a wireless subwoofer
3.1 = front left/centre/right and a wireless subwoofer. Centre adds clear dialogue
3.0.2 = front left/centre/right and front up firing left/right – minimum for Dolby Atmos
3.1.2 = adds a wireless subwoofer
5.1.2 = front left/centre/right, front up firing left/right, rear left/right and a wireless subwoofer. This is what most Dolby Atmos streaming content uses
7.1.4 = front left/centre/right, front up firing left/right, rear left/right, rear up firing left/right and a wireless subwoofer
7.1.4 is as good as Dolby Atmos currently gets from a 4K Blu-ray. The content needs to have Dolby metadata encoding and passthrough to the soundbar for processing. Recommend for all OLED and NanoCell 2020 TVs.

We can only assume that the Dolby Atmos versions use HDMI 2.1 and eARC. You will need the proper HDMI 2.1 Ultra High Speed rated cables for 8K TV and Premium High-Speed HDMI 2.0 for 4K. Read more here.
