Zoom function does not work properly

[ferxxx]

Can anyone confirm, if after the last firmware update "180902_0153_r13" (BETA version), that was released a few days ago, the zoom function now works correctly?
Or is it still stretching the image laterally, distorting the film?

This say in the new changelog:

- Improvement: Pro 4K: Aspect ratio is now correctly detected (and correct
  video zoom settings are applied) not only for files (as before), but also
  for Internet video streams (when played via Dune HD applications).

I want to see a movie with aspect ratio 21: 9 (movie film format) and take it to a 16: 9 aspect ratio, to look at it in full screen but without distorting the image, and I understand that currently, the zoom function in the dune hd 4k pro does not work correctly, and what it does is just stretch the image laterally.
I would like to know if after this update this bug has been solved.

Thanks in advance.
