I think that the book is a wonderfully produced work for anyone who is interested in Wilde or Dorian Gray in particular. It has fantastic portraits, photographs of period objects (like a Vesta cigarette-case, a hansom cab, a brougham, styles of clothing) and scenes from the novel in painting or sketch form. It also has notes regarding events and people that are being referred to, often quite obliquely.

There are only 62 textual changes, most of them very minor, and so I think that talking about a "different book" or a "different version" is a bit disingenuous. The casual reader wouldn't even notice the changes, and even a careful reader would probably miss about 90% of them (e.g., in one spot, "him" is replaced with "Gray" to avoid confusion).

The "Uncensored" tag is just yet another marketing ploy.
