Only on SCTV Central, but that was a long time ago and not the star logo but ‘SCTV’ text in the top-right corner.
It could have been a movie that broke away from the Seven schedule, or it was just sourced differently? They still insert their own graphics when it’s breakaway programming (see below example from 2020 after 7mate changed their logo and SCA still had the old graphics loaded)
That is how an affiliate should watermark their station. Simple. Not the rubbish WIN expose their viewers to. WIN was just as good as Prime Television back when the stations first started having watermarks
