Would the Apex Width be the same on a Full Hollow as on a Wedge with both grinds having the same bevel angles?

I have to ask this question because the more i think on it the more complicated it is.

An extra hollow grind has to have a finer edge than a near wedge doesn't it? My reasoning is not based on maths but on my face telling me what i have felt over the years..

I would be interested in your thoughts..Thanks
