OP you must do whatever you feel is appropriate if the neg and subsequent print(NB this is the real test of the neg) isn't what you want it to be but the scan if it's a true representation of the neg does show highlight detail in my opinion. I am basing this on the white dress where except for direct sunlight there appears to be all the highlight detail I'd expect in the light conditions. The two area where there is no detail is the hip area and the forehead but both areas have direct sun on them and become close to specular highlights.

The shadow detail in such contrasty light appears pretty good to me as well
