I missed this thread and was not aware of the issue until I read Mark's article yesterday. Ugh! I printed a 30x40 print for a client last Friday and I noticed that the color was very slightly off, but just chalked it up to a profiling issue. (New paper, Epson Legacy Baryta.) After I read the article about the printing glitch in CC 2015.5, I reprinted the image with PS CS6 and was amazed at the difference. Yes, the color in the new print was very subtly different, but the tonality was even more different. The highlights were brighter and warmer in the new print.
