There is some misinformation online regarding eARC and HDMI 2.0, suggesting it's limited to compressed Dolby Atmos. It's not, based on its implementation.

The only time this is the case is if it was an original ARC port that received a firmware update to make it eARC, which is not the case with QMK series.

In the case of TCL QMK series, per RTINGS, the eARC port will pass full uncompressed Dolby audio with no reduction in quality.

You'll definitely want to plug in a game console to the HDMI 2.1 tv port to get 120fps & VRR, but if it's a soundbar use case, it will pass full uncompressed audio in the 2.0 port.
