Geordi, Raffi, and various background characters on Utopia Planitia and the Verity are wearing them.
Unless we actually see those people in the show wearing those uniforms in a flashback scene, it's not canon. Just like with the Verity being an Odyssey class ship, the comic artists probably just extrapolated things based on the information they had at their disposal (i.e. Picard's admiral uniform = 2385 duty uniform because there's no other evidence to the contrary yet.)
