Is compression ever good if you have a system with sufficient headroom?

Sonos has a menu for choosing the type of compression applied with 3 choices; automatic, no compression and compression. It includes this "Sonos presets the best audio compression for product Line-in."
I'm thinking that the purpose of applying compression in general is to prevent distortion from occurring in systems with low performance amplifiers that are unable to reproduce the peaks cleanly. if that is the case the Sonos software would be elevating the lows and clipping off some highs to prevent that from happening. But if you have a high performance system with a great deal of headroom should you avoid the auto setting and select "no compression"? I have to say that with about 30 minutes of careful listening I could not distinguish a difference between any of the settings (listening to Spotify Premium through Mac 300w amp/Focal Spectral towers).
All thoughts/advice welcome.

The Sonos website has a short article on those settings: https://support.sonos.com/s/article/1080

This mentions network issues and delay/synchronization with video as well audio quality. Depending on how the compression is implemented, it could be more pleasant for lower volume listening. I'd just turn it off.

Edit: The article may be about data compression as dc suggests. My remark is about dynamic compression.

I may be mistaken, but I think that's compression of data volume (lossy), not output limiting.
