There was never 21points manual gamma in the JVCs, only 12point.
The manual tri-band gamma controls in the new JVCs are very good for small adjustments. They replaced the 12point manual gamma controls that took ages to get right and couldn't solve the gamma droop after a while by a 33points automatic gamma control that's so good that you don't need an external LUT anymore and that fully solves the gamma droop, at least for a few thousand hours. So yes, you have to pay less than $100 for a Spyder meter, but then you can save thousands on an external 3D LUT which isn't necessary anymore. You also have the 12points manual gamma in the software if really want them, but apart from targeting really exotic curves I really don't see why anyone would want to use these given how well the autocal performs.
I used to be very critical with the JVCs calibration-wise because of the gamma droop, their poor CMS that isn't linear, their undersaturated standard color profile which was uncorrectable even with an external 3D LUT and their manual gamma controls that only worked correctly every other generation, but since the standard colour profile is now slightly oversaturated and the JVC Autocal solves all these issues, I'm a happy camper. They haven't fixed their CMS but it's not necessary anymore, so why complain?
The only downside - apart from the lack of proper documentation - is that we have to find a relatively accurate Spyder, but it's possible. Even the not so good ones like the two Spyder 5 I've rejected are not appalling and would provide a significant improvement that would make 90% of users happy after a few hundred hours. I only rejected them because they were worse than my golden Spyder4, not because they were bad for their intended use, which is to provide along with the Autocal software a way to get 80% there calibration-wise.
