You are making assumptions about the user and the use of an incident meter without basis.
All ANY meter does is provide a reference point with each reading. It is up to the user how to position the meter and interpret the results.
ANY meter can be used well or poorly with results to match.
I'd suggest that incident meters require less interpretation so for the grand majority of people, regardless of film type, they will typically provide better results.
Spot meters are very handy but they are specialty tools that require special skill and experience. Reflective meters of all types require more interpretation, even an F6 Nikon with all the fancy algorithms gets fooled.
