I think lower alcohol BDSAs with lower finishing gravities (sub 1.010) will be fine with lower carbonation levels. But higher gravity versions, the example I brewed finished damn close to 12% ABV with 1.012-1.014 as the final gravity, I think that around 2 volumes, and the alcohol that high, made it seem very syrupy and sweet, and I really think it was the alcohol content making it seem that sweet (particularly at 1.012-1.014).
One thing I was listening to recently is, its not always what the volumes in the bottle is. If you pour a highly carbed beer very aggresively, you'll knock out a lot of the carbonation, I pour my bottled ESB very aggressively deliberately to try and get the cask level carbonation. Pour the same highly carbed beer very gently, just enough to build the head but retain the carbonation it'll come off as very crisp and pop. I think pretty much any of the major Belgian styles are better with higher carbonation, and if I open one and it seems WAY too highly carbonated, I'll just pour the bottle hard for the first half of the bottle and knock out some of that carbonation.
