Wow, I just checked and you're right. I find it fascinating that all of this modern software continues to support JPEG 2000 in such a buggy state. Or maybe it's the file itself that's corrupted? I don't know enough about the file format to say.
1. Per Photoshop, "The embedded ICC profile cannot be used because the ICC profile is invalid."
2. After using the OS X Preview.app "Assign Profile" command to replace the embedded ICC profile with the system-supplied sRGB profile, the image displays correctly in Safari.
3. The ImageMagick display command is apparently ignoring the embedded profile and assuming sRGB, as it continues to display the image correctly even when I replace the embedded profile with an obviously incorrect (but valid and correctly interpreted by Photoshop and Safari) profile.
