Same problem here. In Develop persona the Histogram's display is skewed to the left suggesting that blacks should be clipping while it is not true. I have opened the same photo in Lightroom so you can see the problem. In both Histograms, it is the same RAW photo without any adjustments.
Photo looks the same in both applications it is just the Histogram that it is skewed to the left in AP.
However, when I switch to Photo persona the Histogram looks like the one in Lightroom...
This photo was taken with Nikon D7100, but it is the same problem with photos taken with Nikon D750.
