Yup, going back I used the same steps:

- Removed the visible company name (kept schema)

- Prompted both (they still reported the visible company name even though it was removed, but not schema)

- Reindexed the page

- Verified it is reindexed (through URL inspection tool that shows the saved version of the page)

- Prompted both, and they said there was no company name on the page.

Yes, Google saved the schema (verified through Search Console)
