I see several have beat me to it, but it is worth chiming in that the red circled ships in the fleet shots very much have the visible Akira saucer notch. Beyond that, I couldn't honestly swear I could tell much in the way about the details of ship class, but I can certainly see that these aren't Excelsior saucers aka Centaurs. 

But it is in line with the lighting not being consistent in various shots, especially in the fleet shots.
