Well as mentioned originally I tested this on my Window 8.1.1 64Bit machine with SQL Server 2008 R2 (SP2) 64Bit which also happens to have the Hyper-V Manager (client) installed on it.

SQL Server is running directly on my physical machine it is not virtualised.

Therefore given the above if the SQL Servers SP is going to still saying that it running virtual that makes the results of the SP unreliable as in the above case it is simply not true.
