I believe that the hardware between the Go Color 7 gen 2 and the Go 7 Monochrome are the same except for the screen.
Go 7 Monochrome specs can be seen here if you scroll down a bit:

No idea about the stock firmware though. Purely speculatively I think they're the same given that I see some options for color settings in my Go 7 Monochrome that don't actually seem to do anything.
