Just quick replay (I did not test it :-) ): - tiff is"container of images" and AFAIK each image can have its own resolution (DPI is just information for correct printing/displaying of image) - tesseract should read multi-page tiff image-by-image and process it individually (including DPI information)
=> If each page/image in multi-page tiff have DPI info, tesseract should process it correctly I am not sure how "--dpi" option would work in this case - IMO multi-page tiff scenario was not considered.
