Hmm...it may not be canon in the sense that we did see it, but also it's not necessarily a contradiction, because the shot with the noticable ceiling is from the second pilot film and therefore before
the Bridge underwent several upgrades and changes.
Thus, for the regular series, the inner Bridge dome may have looked like what you designed, we just never got to see it.
But then again, there is this shot from Is There In Truth No Beauty?.
Obviously, where the bridge segment tops meet to form the "half-dome", the ceiling then shoots 90 degrees upward in a cylindrical fashion. This makes my version non-canon.
