I would have to agree with Eldartford that before and after bit by bit comparison would answer the question. I would not be surprised if it did make a change.
Surface texture (or polish) should make a difference in the refraction properties of the whole disc. Although the CD surface looks very polished, there is a measurable texture or finish to the surface. This treatment could "theoretically" reduce that texture or further smooth the finish and allow for less reading error.
Also polycarbonates and acrylics will absorb molecules, water/O2/CO2 etc. So again it is "theoretically" possible that the solutions are altering the base properties of the optical layers.
Both optical clarity and surface finish are easily measured, (with lasers no less) hence, the manufacturer would have no trouble establishing a claim on that basis, if true.
But hey, I am a Package Designer, so what the heck do I know. I can count on one hand the number of check sum errors that have shown up optically reading untreated storage media over and over again.
