That's why I was intrigued - I inferred that your fix was to use an sRGB
profile in the JPEGs rather than CMYK.
However, there still sounds like an issue somewhere - the engine should
cope with CMYK, so assuming there is a profile in the JPEG for CMYK it
should display similar to Preview. I know CMYK JPEGs are a bit gnarly so
having an example which doesn't work quite right might help them work a
little better and more consistent generally.
Of course, I could have misunderstood entirely!
