To answer your question, yes, the draw weight at brace would be a touch higher at the higher brace height, but at a half-inch higher, probably only a half pound or so, not enough that you would likely notice. However, that does not translate into increased draw weight at your normal draw length.
There are a number of videos on Utube that come down on either side of this questijon, but here's my take on it as well as the findings of a couple of utubers. (Archery 101: Does Changing Brace Height Change Poundage," and Arch4archery: "Recurvbe Bow Brace Height"). They both show with pretty accurate measurements that raising the brace height has no affect on bow poundage at full draw.
Raising the brace height (let's say an inch) is akin to drawing the bow an inch. It begins to flex the limbs, putting a little more tension on the string, i.e., increasing the draw weight at brace. Again, by a small amount.
However, at full draw, the draw weight is virtually the same regardless of the brace height because the higher the brace height the less you draw the limbs to reach full draw. For example, if your brace height is 7 inches, you pull the strting an additional 21 inches to reach 28-inch draw. However, if the brace height is 8 inches, you pull it only an additional 20 inches to reach full draw. The resulting draw weight at full draw is virtually identical.
This explains how some folks micro tune their bow to the arrow by twisting the string up a few turns to bring a marginally stiff arrow into line. It increases the poundage at brace, be it ever so slightly. At the same time, this decreases the power stroke such that the arrow speed remains virtually unchanged. If anything, the slightly increased power stroke of a lower brace height increases performance just a tad more than an increase in brace height, but it's so slight it is very difficult to measure.
