It does truncate bit depth when creating the 16bit unencrypted contend from HiBit. Maybe they use it also while applying their apodizing lowpass on existing 16/44.1 material. Using dither is a must and using a noise shape is best practise. Good noise shaped dither can raise the dynamic range before you hear the noise of dither a lot. I am pretty sure there are not many recordings in the world that really can stress the 16bit noisefloor then. Good noiseshaping relates to the working of your ear, the ATH. HF noise is less critical as it looks like spectral. You won't hear it.
Just for fun: http://www67.zippyshare.com/v/o4e9iWZY/file.html It contains 2 silent files. One with flat dither and one with ugly looking foobar noiseshaped dither! Already cranked up by +45dB!! Try to hear the noise in your listening position and realize what of your recordings you can listen with +45dB without your speakers explodes.

Your gear will most likely already work in 24bit. Even Meridian will use flat dither for that.
