You cannot prove that it effected one team more than the other. It's your biased opinion. I'm not saying it did effect one team more than the other... You're so ingrained with your theories that you believe them as facts.
I think the one major thing that hindered Iowa in that game was not being able to see Iowa State's film, which is big, but I can't really think of any other. It hurt Iowa State in many different facets. Having to get all ready for the first game of the year and play hard for 5 minutes, wait around for hours, then completely shut it down hurts. Not getting reps from guys that would be seeing their first college minutes hurts, especially on the o-line. It for sure hurt both sides, but likely it hurt Iowa State a bit more.
