The actual RMS when measured on a true RMS meter would be 240/2-0.6V. There is a tiny drop across the diode.
The diode drop means nothing to us working at mains voltage but it would matter if you were working with 3V RMS from a small transformer or making a doubler from the heater supply on a valve amplifier.
