Too right. It's just that these ones pushe the saturated blue into
purple. We don't get this when we produce our own profiles using the
FOGRA data or using our own measurements even with extra chroma
( Profilemaker 5 as opposed to the Heidelburg software that I believe
was used to produce the ECI profiles).

Scary......but I'm not getting such pronounced shifts in CS1 or CS2.
