The reason is that the DN32-LIVE card is installed in the console and sold as a complete package. Once purchased the customer may at any time decide to swap the LIVE card for an ADAT or DANTE card etc, so as the card is not a committed part of the console's hardware, a printed "LIVE" logo on the console would not make sense. 

Similarly, a customer with an older standard M32 or M32R could purchase the DN32-LIVE card as a finished goods item and fit it to their console to obtain the same advantages of an M32-LIVE customer, however his console would not have the same styling (plastic keys vs rubber keys) for these reasons the decision was made not to give the LIVE series consoles a "LIVE" logo.
