Very disappointed about the change of the video contrast in BD version, because we can"t see nothing in dark areas.
So for my best anime of 2023 (this show deserves really to be more popular), I want to do something :)

To fix the the video contrast, I used this simple script:
https://github.com/dubhater/vapoursynth-adjust/blob/master/readme.rst

With this line: adjust.Tweak(src, cont=0.87, bright=13)
I achieve to get a better result than the BD:

I could not get the same color than the TV version, there is still more saturation but for me it's enough.

Luckily, i found these encode scripts with a OK filtering, especially to fix a lot of aliasings:

So I just added the contrast fix, before all filtering in the script.

The filtering was done for TV version but it seems there is not really difference after checking.
Here is the comparison TV/encode (done by the author of scripts):

I planned to encode the rest of episodes with the same settings above, but it will take more times, knowing that the encoding of the 1st episode took more than 5 hours and with my work...

You can make the BD match WEB exactly if you do a full -> limited range conversion
Thanks RainingTerror for tips, it works very well

So let's get restarted the encodes :(
