You literally can not distinguish 192 Kbps Opus from true lossless. Not even with movie theater grade speakers. You only benefit from lossless if you’re editing / applying multiple effects, etc, which you will not do at the receiving end of a Bluetooth connection.
Opus is great, but there is no option to make it lossless, like what WavPack (also a free-as-in-freedom codec) provides for example.
Transparency is good enough, it’s intended to be a good fit for streaming, not masters for editing
Why not have the option for true lossless available so that Bluetooth can be scaled up to sound good on even the highest end of systems.
