Update : thanks for the suggestion about changing the library type, after a new try it seems to work !
I the corrected filenames for the thumbnails in a "home videos and photos" library (with "-poster" at the end this time) and now it does work, every video has the correct associated thumbnail \o/
So I tried again with a new "mixed movies and shows" library, but it still doesn't work there, all the videos have the same thumbnail.
¯\_(ツ)_/¯
So not entirely solved but at least it's a usable workaround
