Are there any studies demonstrating an observable difference in such a scenario?

My point is that there are no studies demonstrating the absence of such issues. Anecdotally, my Bluetooth headphones certainly seem to sound better with a FLAC source.
Until it is resampled in the noisy OS mixer and/or lossy compressed again to be sent over Bluetooth. Very few ABX studies consider the effect of such modern "digital signal chains", especially transcoding. It's much better to start with FLAC.
