Lossless is understood to have a bitrate of at least 1411kbps, or about 1.4Mbps.
Theoretical sustained bandwidth capability of Bluetooth on the 2.4Ghz spectrum is 1Mbps, but in practice it’s a chunk lower in part due to overhead.
Even if we assume if you could just cram a higher bitrate through a smaller bandwidth (spoiler, you can’t), everyone would be up in arms about Apple lying about lossless and class action suits would ensue.
That said, you can’t. This is not like your internet connection where you’ll just be buffering for a minute.
As for what is and isn’t perceptible, I think you’re mixing up your tonal frequencies with your bitrates here.
No, lossless isn't assumed to have a bitrate of at least 1.4Mbps.
Yes, lossless compression exists.
No, I am not mixing up bitrate and frequency. Yes, with a typical codec the difference between 700kbps and 1mbps is almost certainly imperceptible in almost all conditions.
