Sure, they might have been down on power, but not by any amount that was extremely obvious to the daily-commute driver. No apparent drivability issues with gunked up valves - they all started fine, idled fine, ran OK at part throttle around town, etc.
I'm not saying that these deposits are a good thing, but the people that shriek in horror at photos like the one shown above should remember that we've been living with IV deposits for many, many years.
