Great question actually. While there may be times that I’m actively looking for livery errors, most of the time something I’m just looking around on the standard outside camera to enjoy the livery, and then I might find an error out of nowhere.
I second that. I think people who have great attention to detail like you are just trying to be helpful by identifying a simple mistake that can be corrected.
If you feel something’s not right with a livery, you go ahead and say something. Who cares what others think and/or how significant it is. It all boils back to making the sim more rea- I mean more reflective of reality. No need to settle for a mistake like that. That’s injustice to an airline.
