That's not the information I've seen. From what I've read a fully-loaded takeoff and climb would burn so much fuel, far more than a typical profile, that it would still not have been able to break records set by the migs.

That sounds dubious to me. The SR-71 had some massive tanks and the idea that it couldn't accelerate to full speed on one tank seems unlikely. Even if you account for the burn in climbing to 50k feet ASL it seems like it has to be underselling the Blackbird quite a lot.

These two claims aren't mutually exclusive.
