The SLV is the only version that includes the complete argument between Kirk and McCoy ("And another thing...." "Get out of here, Bones."), isn't it? That's one of my favorite scenes in the whole film. I don't know why the theatrical and DE cuts removed it. It requires no effects, after all...
My guess would be because it seems disrespectful and it makes Kirk look bad, and it somewhat contradicts the earlier scene in the Transporter Room when McCoy beams aboard and is greeted by Kirk. In this scene in Kirk's quarters, Kirk does not seem to need Bones "Badly!" anymore, for the moment. So, Kirk needs McCoy for the mission, but not for his personal or professional life, until McCoy points out Kirk's obsession with getting command of the Enterprise and commanding the Enterprise.

James T. Kirk: Yeoman?
Yeoman: Yes, sir?
James T. Kirk: What was the problem down there?
Yeoman: He insisted we go first, sir. Said something about first seeing how it scrambled our molecules.
James T. Kirk: [to Rand] Has a familiar ring, doesn't it? Starfleet, this is Captain Kirk. Beam that officer up now.

James T. Kirk: Well, for a man who swore he'd never return to Starfleet—
Leonard McCoy: Just a moment, Captain, sir. I'll explain what happened. Your revered Admiral Nogura invoked a little-known, seldom-used reserve activation clause. In simpler language, Captain, they drafted me!
James T. Kirk: They didn't!
Leonard McCoy: This was your idea. This was your idea, wasn't it?
James T. Kirk: Bones, there's a thing out there.
Leonard McCoy: Why is any object we don't understand always called a thing?
James T. Kirk: Headed this way. I need you. Damn it, Bones, I need you. Badly!
