The format command has effects only for the display in the command window. It does not concern the values inside the code. In your example format does not influence the value of T1, only the display in the command window.
The value displayed for CT is the handle of the text object. The format command is not useful here, but set a semicolon at the end of the command to suppress the output to the command window:
CT = text(X6,Y6,num2str(N3),'FontWeight','bold','fontsize',12,'color','r');
