I might be wrong, but I think the asterisk simply means that what you are seeing in the image needs to be saved.
After completing my work in Camera Raw I click the “Open Image” button, which opens the image in Photoshop.
In Camera Raw, what working space do you have it set for processing? If Camera Raw and Photoshop are both set to sRGB, you don't have a profile mismatch. If Camera Raw is set for any other space and Photoshop is set for sRGB then yes you have a mismatch. So, what is Camera Raw set to open as?
Yep, that's the answer. I didn't realize that I had a choice regarding color profile in Camera RAW. I looked around and discovered that the thing under the photo that looks like a web link brings me to a place where I can choose the color profile. And, you are correct. There was a discrepancy between the profile that was in Camera RAW and the profile that was in PS. A couple of clicks of the mouse and the problem has been solved. Thanks for your help!!!

I still don't undersand why that "thing" can't be a button.
