After some searching I found a patent I
think may be related to this
https://patents.google.com/patent/WO2020225109A1/en because it uses the phrase "Holocam", is German and was filed by Audi (the press release mentions automotive applications as the primary initial use case). It's a translation from German which makes it a bit tougher to parse than the usual patent.
The total lack of any deeper information beyond the bold yet vague claims in the press release is frustrating. The PR makes it sound like a miraculous breakthrough destined to change everything. The source release on the Zeiss site only adds two bits of info.
> "The transparency of the holographic layer has only a minimal effect on the brilliance of the image reproduction. It is also possible to detect spectral components as additional information to complement the visible image. The resulting data provide insights into environmental contamination such as air pollution and UV exposure."
However, experience shows that in reality bold+vague claims like this inevitably come with significant trade-offs and constraints which limit its applications (little things like cost, power, fidelity, size, speed, etc). This is especially true in early implementations of new tech. That said, it may still be both interesting and useful. Unfortunately, we have no way to even think about how it might be useful because Zeiss marketing has chosen to play 'hide the ball' instead of just releasing a technical explainer outlining relevant trade-offs, limitations, etc.
If I was talking to someone from Zeiss my first questions would be about how much the additional components impact the optical characteristics of the glass, what the resolution of the resulting image data is, how large are the components needed at the edges and how far away can they be from the capture zone? Then, of course, how the output of the resulting imaging system maps into traditional camera/lens metrics like f-stops, aperture, imager size/density, gain, focal length, etc. Zeiss is an optics company after all.
