Correct schema markup makes a page eligible for a rich result, but doesn't guarantee Google will actually display it — eligibility depends on markup accuracy and completeness, but the final decision to show a rich result (and its exact appearance) rests with Google's own systems and can vary by query, device, and over time as Google adjusts which rich result types it displays for which content categories. Google's Rich Results Test tool lets a site owner check whether a specific page's markup is technically valid and eligible, which is the correct way to debug rich-result issues rather than assuming any implementation gap based on the search results alone.
Example
A recipe page implements complete Recipe schema (ingredients, cook time, calories, ratings) and becomes eligible for an enhanced rich result showing a photo, star rating, and cook time directly in search results, though Google doesn't guarantee it displays on every query.
