I find your question odd in that the 2x4 framing is usually of the rough opening and is what the window is attached to. and then the returns / jambs are fastened to that framing as well and overlap the interior body of the window frame. And then the casing or trim is mounted to your finished wall surface and 'reveal' is usually describing how much of the return / jamb edge is showing, inboard of the casing / trim.
So I really can't tell what you are talking about in bringing the 2x4 framing up to a laser line. Isn't the framing already in place?
Maybe I'm misunderstanding. I've done many window replacements, modified a bunch of walls and worked with a lot of 'reveals' including building up tiled shower walls with windows in them.
If you are asking how far inboard on the interior face of the window framing your return / jamb boards should be, the answer is 'wherever looks good' and is usually happenstance based on how oversized the rough opening was for the window unit.
eta - never seen someone try to make them all exactly the same, unless they have some sort of disorder.
