Pastry-wrapped bread?

Toast

Hi! I'm trying to recreate a sort of pastry-wrapped bread and was wondering if anyone has experience with this. I was inspired by this bread - there's thin puff pastry wrapped around almost the entire loaf apart from what I guess are score-marks. Will the puff pastry prevent the bread from rising during proofing, or will it expand alongside the bread? 

This is not pastry wrapped bread.  

The photo does not looked like a finished baked loaf.  It looks like a loaf after proofing and before baking. 

The loaf is made using two doughs.  The main dough is straightforward, and formed into a boule.  The second dough is colored with green matcha powder, likely during the mixing step.  The second dough is rolled into a thin sheet, then formed around the boule from the main dough.  Spraying the boule with a mist of water would help adhere the outer green dough to the inner boule.  Then the loaf is scored.  This is what I think the photo portrays. 

The outer green sheet will expand during proofing and in the early stages of baking.  It would be interesting to see a finished baked loaf to see if the outer sheet cracks or tears.  To me the photo shows an unbaked loaf. 

No puff pastry involved.
