In 2009, we got a copy of the 1988 book on Weiqi Fayanglun [LIT. 3], written by Cheng. As far as we can see, in the introductory text to problem 120, he mentioned that White has one more stone on the board. With the application of area scoring, which is typically used in China, this results in an advantage of one point for White. This is equivalent, under Japanese-style territory scoring, to one Black stone having been captured by White.
