Url Performance Report displays not all URLs

Hi all! I need to get all URLs by company, where my videoAd had been displayed. If I see it from AdWords web interface - for example for 25.06.2018 - there is about 4000 youtube channels, where AD been displayed. But if I get it from Url Performance Report by script - there only 180 urls(((
