هَذَا الْكِتَابَ قَرَأْتُ.

Fronting the object highlights a particular book. In response to a question choosing between two specified titles, the order usefully focuses the selected alternative. It does not, by itself, assert that the speaker has never read any other book.
By contrast, مَا قَرَأْتُ إِلَّا هَذَا الْكِتَابَ overtly excludes other books within the contextually relevant domain. The analyst must still specify that domain before claiming universal exclusivity.
