I agree to a certain extent with you Martin.
The arguments I have heard for CD Disc treatments are;

1) Not all the Laser Light will be reflected back straight to the Receiving Diode, these treatments help to Block the stray Light from ending back in the Receiving Diode when it shouldn't.

2) The RF Waveform coming from the Receiving Diode (the 'Eye Pattern') is 'chopped' top and bottom to obtain a nice Square Waveform. These treatments help, should the Eye Pattern have become distorted by the stray reflected Laser Light causing the 'chopping' to further distort the Digital Signal so more Error Correction needs to be applied.

I think Digital is not as 'Grey' as some think but...............
Personally I am yet to be convinced. As many have said on here these treatments are often the price of a Music CD and I know where my money will be spent.
