The chords don’t need to be different. A jazz blues would also (usually) be characterized by a walking bass and lack of a backbeat on the drums. Thelonious Monk’s “Blue Monk” is an example with pretty standard blues changes. That being said, there are infinite variations of blues chord progressions in the jazz canon. Some great examples are Charles Mingus’s “Goodbye Pork Pie Hat,” and “Nostalgia in Times Square.” Then you have examples that are closer to standard blues but with a few substitutions, like Joe Henderson’s “Isotope.”
