I don't have Sony specific AF knowledge, but the following applies to modern mirrorless cameras in general and should be kept in mind when evaluating the plugin result:
- The plugin relies on documented tags from EXIF metadata (maker notes section) to retrieve AF information. If the camera does not maintain these fields properly because it primarily uses other AF related sections in an undocumented part of maker notes the results of camera (or maker's RAW converter) display and plugin may differ.
I am using OM-1 and can see a similar behavior. For OM-1 predecessors E-M1, E-M5, E-M10 results are identical.
There are other Sony AF visualizers eg. https://github.com/SK-Hardwired/s_afv.
You might want to check if these show differences in AF position as well.
- For cameras using contrast AF, the center dot displayed by the plugin is misleading*. The focus point is somewhere inside the red box. Accordingly, on camera display the focus point is somewhere inside the green box. Both red and green boxes in the images do overlap, so in my opinion the difference is acceptable.
*That's why I have removed the center dot for Olympus and OM System cameras. I am neither the inventor/author of the plugin nor do I have specific knowledge about Canon/Nikon/Sony etc. so I didn't want to touch the logic for other camera makers.

Gotcha, thank you very much! I will try the visualizer instead.
