If you had seen my website (brahmamic.com) recently, you will notice that I have been offering to calibrate third party microphones including diy microphones. I also recalibrate brahmas more than two years old.

Try again: I have an older Oktava MK_012 4D. I bought it relatively cheaply on eBay a few years ago; it came without any software or digital calibration data; I think Oktava don't offer anything more than paper frequency response traces for each capsule. I think it has a larger capsule array size than the MK-4012; in the MK-012 4D, the capsules lie on a sphere of about 96 mm diameter. Fons Adriaensen kindly calibrated my Oktava MK_012 4D for me. Calibration made a big difference; without calibration, directional cues were almost non-existant. But the same recordings, reprocessed with the calibration files, had directional cues, at least at mid- and lower frequencies. Fons, and Angelo Farina, explained that the mic could not resolve directional information at higher frequencies due to the large array size. I think the capsules on my Oktava are not very well matched (it is maybe 20 years old), and it really needed the calibration. I love the quality of the sound captured by the Oktava, especially for classical chamber music and choral music but, to be honest, I use a Brahma more often, because of its much better directionality. My recommendation is, if you have an Oktava MK-4012, get it calibrated. In my case, it made a big difference. Fons Adriaensen in Italy calibrated my Oktava. I believe Richard Lee in Australia might still offer a calibration service, though he appears to be less active on the internet these days, and I think Core Sound in the USA also will do it - they used to say it on their website, but I haven't checked lately.
