Bose TV Speaker and eARC

[Purdnost]

I own a Bose TV Speaker. I can’t find any information as to whether or not it supports eARC. If not, is there a firmware update that will enable it?

I recently purchased a LG CX TV that offers a setting to enable eARC. My Apple TV 4K supports eARC.

Everything is connected with HDMI 2.1 cables.

I just need to know if there is any advantage to enabling eARC on my TV with my current setup.

I have vaulted ceilings, so I don’t need Dolby Atmos... but I would like the quality and speed enhancements that eARC provides.
