It is unaffected if you assume you're using the same seat post. The seat tube length and your saddle height are both measured along the line of the seat post, regardless of its angle. The only way I can think of that would slightly lower the amount of exposed seat post would be if you went from using a laid back seat post to using a seat post with zero set back. This would very slightly increase the amount of exposed seat post a given level of saddle height.
