AFAIK, there was no change on the finish of the Master 8 Days.
On the RG version, the dial has a sunburst finish, as you can see on this bad picture taken with a flash:
On the SS, I think ( not sure ) that the dial has a sunburst finish, too:
The thing is that I don't have good quality pictures of this model, so it will be difficult for me to go deeper in the details, but if you saw this kind of finish in some macros, then I highly doubt that the dial of the Master 8 days has varied.
The thing is that this kind of detail is noticeable in some light conditions ( strong light, like sun or flash, for example ).
If you find one, ask your seller to provide you some good macros.
Best, and sorry to not have been very helpful on this matter.

This borders on blasphemy, so please don't send the Spanish Inquisition! Nicolas, I think you posted a picture of the Platinum version and not the SS one... the 'poor man's version' has a different day/night indication (whereby I prefer the SS one!), please see on my version (apologies for the extremely lousy pictures!).
As far as I know, only black dials within the Master Series don't have the sunburst finish (unfortunately!). I tried to make them visible on my photos... So Dan, either you've seen another special edition (which has a 'matt' dial) or the pictures couldn't catch the real beauty of the dial. Furthermore, the small second hand subdial should have concentric rings, yes.
A beautiful watch, from both dial and movement side! Everything's just 'right'!
