Truss systems are "egineered" for the task (or at least they are supposed to be). Assuming these were designed for the purpose and installed as specified, there is little to say about them unless they are visibly in the process of failing.

If you found no signs of distress or deflection then I would think you would have no comment to make about them as a home inspector. The fact that you (or I) might be unfamiliar with this particualr truss configuration is not in of itself a "defect".
