DS9 had frequent if oblique references to it as well, Quark’s Bar had holodecks, I think Major Kira threatened to break his arm if she found out she featured as a character in one episode.
Possibly the same episode, but some creep was trying to get a holodeck session with her likeness, and when Quark managed to get her likeness, the revenge was to corrupt the holodeck program to put Quark's head on the body: https://www.reddit.com/r/startrekgifs/comments/i8hilq/cant_d...
