There is actually no guarantee whatsoever that an automatic "calibration" will be correct. Let me explain this as simple as I can:
A calibration of a display is all about comparing it to a reference, which is usually Rec.601/D65 or Rec.709/D65 in this context (for the BVM-D series, I'd highly recommend sticking to Rec.709). When measuring in CalMAN, you have the option to either measure all the legal values or just a limited selection of it. Now, if you do have experience of this subject (which I do, as I do have both the right knowledge and equipment to get paid for doing this), you ultimately know that you only need to measure a certain amount of values which will help you to keep track but everything you're doing still affects the entirety of the image. Therefore, what you're using to measure the display (software, colorimeter/probe, signal generator etc.) are all tools, what makes the calibration is the person behind it.
For instance, if the BKM-14L measures that the white balance at 0, 30, 50, 80 and 100IRE are all perfect, that by itself doesn't mean that you'll get a perfect greyscale as it doesn't know anything about the entirety. There is also no guarantee whatsoever that the adjustments the probe have kept the gamma curve intact (which is critical for CRT displays) and even if it does find issues, you don't have the control to make compromises as it's all done automatically.
Take a look at this guy:

I know he's a great photographer, and he surely knows alot about color spaces and image in general, but his way of explaining what a calibration is however is nothing but misleading. He's not even changing any adjustments on the display itself, he just creates ICC profiles with the help of a Spyder5 (which, by the way, is among the worst colorimeters you can get these days) and calls it a day. This is NOT what calibration is about.
The only possible way to get an automatic calibration is with 3D LUTs, but even this method is generally speaking very unreliable by now. The upcoming OLED displays by LG (the 8-series) will have support 3D LUTs which can be generated through AutoCal. It'll be interesting to see how it performs but judging on how previous generations have had major flaws with their calibration tools (both 20 point greyscale and CMS are broken) as well as limited bit depth, I have no intentions to believe that the final result will be preferable over what I can perform on one of those displays with about an hour of tweaking.
Calibration is about the image, not numbers. Since a computer (or any application) can only see the numbers, without knowing the entirety, I see the BKM-14L as a very risky choice. Still I will be able to give you graphs later on today on which we will see how much calibration tools have improved over the past 20 years.
