Yes it is lossy. However the important point is whether or not the loss is significant to a listener. After all, all known music recording systems are lossy in one way or another.

Although there is some perceptual coding involved this is not the basis of the invention which depends upon the fact that for audio there is, in effect, no significant audio data (if any at all) related to the final few bits of a 24 bit word which are therefore available for other uses. At least that's how I understand it.
