You don't really need to re-ask this question. It has been asked and answered many times on AVS. The general consensus is that about 10% of the time you get a good result... maybe not the best possible result, but a reasonable amount of improvement. The rest of the time... you get nothing more than twiddled color, tint, contrast, & brightness controls or you get a "calibration" that's worse than the factory settings.
But here's the deal... if you can use the points for something else, like Blu-ray discs or whatever, you'll have something tangible that you can enjoy and it's not a crap-shoot with bad odds. If you have a 3D TV, it's highly likely you won't end up with 3D being calibrated by BB... they have a time limit on how long they can spend on a calibration and that limit is about as long as it takes most pro calibrators to get setup, take the "before calibration" measurements, figure out the best preliminary settings & modes for the TV controls and to just get started with the actual calibration process. 3D calibration essentially requires a repeat of everything done to complete the 2D calibration only with active 3D glasses in front of the meter.
So while "it's free, may as well try it" sounds logical, if there's an alternative purchase you can make with the rewards points that would provide something you KNOW you will enjoy, I'd think pretty hard about going for the "known useful" rewards "purchase" and get a calibration from an independent pro who knows what they are doing and will spend 3 hours or more (versus 90 minutes for BB) calibrating your TV.
