That's inaccurate. Kerry asked for a delay in its release; as Secretary of State, responsible for US embassies around the world, it's his job to draw attention to the risk factors. All reports I've read prior to the release said that both the President and Vice President were strongly in favor of publication. Ultimately the choice to classify or declassify rests with the President.
Remember when Obama blocked the release of additional Gitmo evidence because he claimed it would result in Americans being hurt? I assume the exact same logic was used here to prevent this report from coming out.
I assume Kerry's plea for a delay was a result of the CIA pressuring him to protect their assets which are embedded with embassies worldwide. The collaboration between the State Department and the CIA runs deep, like a mold with many filaments.
We've seen Obama declassify this exact report, without which it could not be published. I'm not sure how much more consistency there can be on this point.

I conclude (rather than assume) that it wasn't, because if it that logic was used by Obama, then this report wouldn't have been declassified.

I don't see any reason to assume that. Its not entirely implausible, but the way that it paints US ambassadors as dupes of the CIA and undermines US diplomatic credibility is also a plausible reason for Kerry to seek to delay it, particularly if there are ongoing negotiations to which the particular issues on which it most damages that credibility may be relevant, and there are numerous other plausible reasons why Kerry might have sought the delay.
