Impact of PhD cgpa in academia and industry
Academia and industry largely do not care about your grades as a graduate student. The only exceptions are certain large corporations that have cutoffs for the GPA for graduate as well as undergraduate studies. [I have worked for such a corporation, so this is not idle speculation.] Even then, such cutoffs are not absolute—if a hiring manager wants you badly enough, they can petition for the requirements to be waived.

Academia does not care about your grades: your promise as a successful researcher and colleague is the primary consideration in getting hired as a postdoc.
