Yes!!!
I looked at the annual average share for KROQ going back to the start...
https://worldradiohistory.com/Archive-Duncan-American-Radio/Duncan-1975-1992/Los Angeles.pdf
The best year averaged a 4.4 and that was 1994. That is less than one out of every 20 people listening to the radio at any given time was listening to KROQ. They cumed just under 14% of the population. That meant that less than one out of every 7 people ever listened to it in the average week.
How can a station "be Los Angeles" if the overwhelming percentage of the population never listened? Well, KIIS had five or six years when over 20% of the population listened weekly. Was Kiss-FM Los Angeles?
I could say that KLVE, which had many years from 1995 onward that beat KROQ's best ones by significant percentages, "was really Los Angeles". After all, the numbers don't lie, do they? Heck, KLVE is in Spanish, and the name of the city is Spanish, so I guess KLVE can claim that LA is theirs. I'll bring it up in the next meeting.
What should really be said is "a bunch of people who loved System of a Down really liked KROQ... years ago". That is closer to the truth.
