More on the 2400 than R800 but certainly a noticeable amount in yellows and some greens. The RGB defaults in ColorSync (which have been pulled from Tiger) are kind of flakey. You’re lead to believe this is used as a default for untagged docs (that’s what it says) but this doesn’t seem to be the case. Depending on what application you’re using, especially Apple Apps, this “default” is ignored and sRGB or your display profile (or Generic RGB) is being used. I’m frankly confused what Apple is trying to accomplish here in Panther but moving onto Tiger, this preference is gone.

Output is fine. Anybody know why? I’ve noticed that even on a calibrated system with ColorSync
