PiCorePlayer - When doing an Insitu Update - Does it load 32 bit or 64 Bit ? ........

Or is PiCorePlayer smart enough to load 64 bit or 32 Bit based on the Hardware you are running?

Also, is there a way to look at the PiCorePlayer Menu and tell whether you are running 32 or 64 Bit?
I went to the diagnostics Page and then Raspberry Pi, but did not see the info there.
