I posted this comment over on the A9F owners thread but it's appropriate here as well:
I thought Vincent's review was really good, detailed and thorough. The only thing that I believe needs clarification is the white point and the slight color banding comments. Determining which white point to use has been discussed for years. D-Nice is one of the "experts" in that area since he's done so much work on that topic and i'm sure he will weigh in on this. But what i believe Vincent "meant", was that Sony was saying using their white point on the A9F, Z9F and the BVM-X300 would make all three devices look the same and I agree it will not which is why you need to perceptually match the three panels if you want to make them look the same because each panel uses a different technology. Whether or not the modified JUDD white point is good or bad or just calibrate to D65 or some other better white point is a topic for discussion. If you get one of the new Sony's and you don't have it side by side with another set you will probably like the PQ just fine unless you have a trained eye and looking for this.
About the color banding, it's not 100% Calman's Autocal causing the problem but probably in combination with the CMS controls. Like any control, even on the LG's which i feel have the best calibration controls, when you start making large adjustments they can generate banding and artifacts which is why you still need someone experienced to use the tool. Just like calibrating manually, you need to make a judgement call on how much to adjust. With Autocal, you can run it and then go in and manually tweak it so if Autocal made an aggressive adjustment, you can run it again and or manually adjust and correct it. The tool is just going through the motions and taking readings and making adjustments and nothing is 100% perfect so just wanted to clear that up. I've used Autocal several times and i feel it works well and can do a lot of work reducing errors on this finnicky set most of the time but you have manual control to finalize the calibration as well. To me, Autocal is a good thing to have if you want to use it Also since it manipulates the user controls, you can document the settings just like with a manual calibration and no backup program is needed.
