Um, no... I have no idea where you got that number.
Since EDR (BT 2.1) added 3Mbps, no faster modulations were added. And that is raw rate without framing or protocol.
BT3.0 added ability to offload actual xfer to another protocol (like wifi) but nobody implements this
BT4.0 just added LE (another modulation, another set of protocols) at 1 Mbps
BT4.2 added a faster rate of 2Mbps for LE
