Okay, I understand that comparing JPG arm to x64 doesn't make sense at this point. However, there is still a problem with comparing files on Mobi. In my opinion, there should be no difference between JPG and PNG. And the app certainly shouldn't show 14% similarity between PNG and the WEBP lossless file made from it.

Right, the image was downscaled by the image engine, please check v30

Definitely better now. PNG=WEBP. When enlarged in the comparison engine, the images look identical. Only JPG to PNG and WEB gives less than 100% compatibility when DCT is set to FP. Which must mean that the comparator engine must strictly use DCT IA, instead of looking at the settings.
And apps still don't want to compare JXL files with others.

The app is behaving strangely. V32 compares some files with JXL and not with others. Unfortunately, I didn't find a rule.
By the way, I compared two completely different pictures, and it turned out that they are 16% similar. I don't know if app should do a test first or if it makes sense to compare the pictures.

I would like to write that everything has been 100% fixed, but I can't.
First, I checked the existing files and jxl compares with everything. Was, ok. I converted the image from jpg to jxl and after comparison it was 100%. I did a comparison with others, then I went back to the jpg-jxl comparison and it was not 100%. Something else happened, bottom selection menu
(what to do with selected files) was under the Android menu (!). I tried to trigger this bug again, but it didn't work.

Still work bad.
I took the photo from the subway: I deleted the previous copies of the lossless files and re-made the jxl, png and webp files. Comparing these files with jpg gave a result of 100%. I killed the app and after restarting it shows 99.9% compatibility.
