Datejust 16234 Help Please

[CNDguy]

Hi nice people!
I’ve recently acquired a great little 16234 DJ with a cream Roman dial.
I wonder if anyone knows if this was a color offered from the factory or has it patina’d?
Also I know that the rehaut is part of the case on a 6 digit but what about the 5’s?. The reason I’m asking is because whoever serviced it at some point has gauged it! I don’t know if you can tell from the picture but I would love to have it replaced.
Anyways thanks so much for taking the time to read and respond!
