I have my music collection sitting as FLACs on my Multimedia PC, connected to my stereo System. I also have a service running that mirrors my music collection by converting it to m4a files and automaticly sends it over to my phone once it connects to my home wifi. I have set up the conversion (qaac64) so the difference between a flac and the m4a file is unnoticable over my bluetooth buds (playing the m4a from my phone).
While I cant hear the difference on my phone, I definiley can hear a difference on my stereo / hifi headphones

Depending on the Bluetooth code flac is indeed not needed.
Something like mp3 happens before it goes over the air unless you have higher codes like ldac
Or SBC-XQ
