I hear you and many do not understand about ventilation and the dynamics of a home. This one you post is not so bad as the ones I see around here are unbelievably bad.
Did you see any mold like stains or blocked ventilation?
In order to describe I we need to see the entire picture.
To be honest I would not make a huge deal over what I see in this pic. (now this is like 5% of the attic, are there soffit vents blocked? how old is the home? Any visible knob & tube?
I would note unprofessional installation, uneven distribution and recommend someone competent would review for properly installing.
I would note the types and approximate depth R value.
