I'll admit that blue must be way out of any gamut.
It is plain to see that some compression is going on. Perhaps Photoshop is
using the PMS Lab values assigned to each spot channels as a Source in the
conversion and is matching to whatever CMYK working space currently selected
as the implicit Destination. I'd just wish that was explicit or documented
somewhere.
Thanks for your help,
