I vaguely remember an old post from here showing someone hacking up Bluetooth to give SBC codec better quality, and it only being available on Linux (or maybe it was Linux+Android?)

I’ll try to dig it up and edit it in here, as I think it was a great hack

Definitely, having just bought some XM4s I was kinda taken aback by having LDAC automatically pop up in my audio settings. Very neat to see support being that seamless!
