Yes, I have looked at hundreds of gen pics by now and sometimes the CP looks superflat and sometimes it looks like it is a little raised in the middle. I can reproduce that with my 000 but I remembered that people are modding their rep CPs to be flat on the top to look gen..
I kinda got scared that I may have an unfinished brooklyn bridge movement inside.. Unfortunately the caseback is too tight and my ball made of duct tape didn't do the trick. Thought that maybe the CP is an indicator whether theres a stock ETA movement inside or a finished one, but it seems there is too much variance judging by the pics of gens.
