That wasn't the Venture. The Venture was from The Way of the Warrior and still had the phaser banks on top of the nacelles that were added onto the model for its turn as the future Enterprise in AGT. The ship in my post clearly does not have phaser banks on the nacelle tops. Indeed, I'm almost certain the ship in my post is CG. Admittedly, much of the final battle in WYLB is re-used footage from other Dominion War battles, I'm quite certain that shot is new.
However, you are right the Venture did not have name or registry on its hull either. So that's two Galaxy class ships without.
Sorry, I realized I was talking about the wrong ship after I posted. See my edited response above.
But my point still stands about the Venture. That was more of a VFX snafu than a legitimate instance of Starfleet not printing info on their ships.
