Having come into possession of some of the ugliest PHP code I've ever seen, I would say it's definitely worthwhile to fix it. Thousand line files with what appears to be random indentation are a nightmare to work with. Meaningless variable names make it a game of mental gymnastics to figure out what $total = $poster * $gmd / $p->lasty is supposed to be doing. This is based off my actual real world usage, taking the hour to reformat a multi-thousand line script which has a habit of exposing interesting edge-case bugs ever couple of weeks has probably saved me far more time than it cost.
