It is definitely painted. But all diamonds are painted to a certain degree. This includes the most well cut super ideal cut diamonds.
Like Garry said, "there is ... a tiny bit of painting"
Nothing to worry about.

In a side note, is that a stone you're considering buying, @Brad Hoem ?
Is there a reason for such high colour and clarity? (E IF)
You could probably drop down to a G or even an H in a very well cut stone and still look identical in colour face-up, and anything better than VS1 will look identical to the naked eye!
Very poor H&A's photos - nothing like Ideal-scope, but any reason why you are ignoring the people telling you to go ahead?
The diamond is currently listed as being in in Mumbai and if anyone else wants to buy it from under you they probably can.
