Roman Numerals with black lining Datejust 116233 - Is it genuine?

[Neilll]

Good morning,

Hope everyone is well.

I have just bought a 2015 Rolex Datejust 116233 with a MOP Roman Numeral Dial from a trusted seller on Chrono 24. I am very happy with my new watch but I am a bit concerned about the dial and hands as my watch has black lining on the hands and also on the roman numerals (pictured below). When searching on google images I could not find any watches which are the same as mine (with black lining) which got me thinking that the dial and hands could be aftermarket even though when asked the seller said that all is Rolex original.

Can someone kindly help me confirm if all is good or not?

P.S this is my first post here so hello to all!

Thanks & regards,
Neil
