Ages ago, I consulted on a case where a converted font was included in a product --- it was even simpler than https://luc.devroye.org/kinch.html since no transformations were applied --- just had to figure out which version of which font editor was used to open up the font file and then which settings were used to re-generate the font in the new format used for the infringing product.
I'm not saying it's never possible in any case, just that in cases where it's not you can't prove infringement.
