Hello, would it be possible to enable camera raw zebras and histograms? Basically the current app feeds you the histogram and zebras for the jpeg preview, not the unprocessed raw values. The difference is that the jpeg preview histograms and zebras gives information on how your exposure set looks for the processed jpeg output, showing what is clipped in zebras, and data distribution for the histogram ect, but if you are shooting raw, this is inaccurate, as you are bypassing a lot of the internal processing in doing so, and oftentimes obscures how much highlight latitude you actually have, which is extra critical, given having less dynamic range to work with on mobile camera sensors.
To test and demonstrate the difference, I shot a test gradient on a monitor, which features increasing from right to left brightness, to show clipping point as a bar. The lower the clipping point, the more widespread the zebras are. On top you have the Open Camera app zebras, and on bottom the zebras show the actual raw clipping point, as shown by editing on Rawtherapee (free and open source raw editor) with no processing that would affect white clipping point applied. If the zebras reflected the raw clipping point, the top and bottom pictures would have the same spread of zebras.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Ignore the greenish tint on the bottom images (Rawtherapee showing actual raw clipping point). That's just the result of a true neutral white balance. Also, top pictures are screenshots of the Open Camera app with the zebras on.
