Unfortunately no. Using the weighted average for multiple roofing materials, it is possible to have greater than 100% reflective roofing for this credit (it's a glitch in the form). The reference guide states you can only earn exemplary performance for SSc7.2 with a vegetated roof.

Must it be a 100% vegetated roof to earn exemplary performance or can it be a Combination Reflective Materials and Vegetated Roof? Current project designed & structured 1/8 of roof as vegetated, 7/8 = > 78 SRI coating & paving. Good, but not exemplary, right?

That's correct.
