Well, you're right that "color balancing" in ACR and others, does cause information loss. It is a linear operation.
Hmm... I think that changing the white balance in ACR could but does not necessarily have to cause information loss. The critical thing is that it happens at debayering time.
Essentially, the white balance setting is three multipliers to R, G, and B intensities as produced by the Bayer sensor. If you go to extremes, sure, you have information loss. But for not-too-big adjustment there doesn't have to be, methinks...
