Thanks for the two images. Each one has a completely identical Adobe RGB (1998) profile with XYX PCS including identical black and white references and simple, identical, 2.2 gamma tone reference curves.
With identical profiles I would expect the RGB numbers to be different betwixt the two but, for example, the green patch numbers are:
no glass: 163, 239, 109. with glass: 162, 239,108.
Makes no sense to me at all, sorry. Either the RGB numbers should be different or the profiles should be different.
Summat's up or summat!
