The biggest limitation is TV series. the metadata id is for the whole show. this will result in refreshing all this specefic show metadata.
Why is that? The way you're looking for the associated metadata item for a folder, you can easily discern the subsequent seasons from it, and then call /refresh only on that metadata item (be it a season or an episode).
The PMS API supports /refresh on metadata items, regardless of whether it's an episode or a season or a movie. E.g.: /library/metadata/:ratingKey/refresh
