Deoldify Vapoursynth filter

I need your support to answer to zspeciman's question.

okay, looking at the scripts.

1st script uses ImageSource, thus frames should already be at RGB24

# adding colors using DeOldify
from vsdeoldify import ddeoldify
clip = ddeoldify(clip=clip, method=0, deoldify_p=[0, 24, 1, 0])

2nd script uses YUV420P8 video source, that is converted to RGB24:

# adjusting color space from YUV420P8 to RGB24 for vsDeOldify
clip = core.resize.Bicubic(clip=clip, format=vs.RGB24, matrix_in_s="470bg", range_s="limited")
# adding colors using DeOldify
from vsdeoldify import ddeoldify
clip = ddeoldify(clip=clip, method=0, deoldify_p=[0, 24, 1, 0])

3rd script uses YUV420P8 video source which is converted to RGB24, but instead of deoldify it uses ddeoldify_main and thus deoldify and ddcolor.

# adjusting color space from YUV420P8 to RGB24 for vsDeOldify
clip = core.resize.Bicubic(clip=clip, format=vs.RGB24, matrix_in_s="470bg", range_s="limited")
# adding colors using DeOldify
from vsdeoldify import ddeoldify_main
clip = ddeoldify_main(clip=clip)

so not really related the first two scripts.

I think that is an issue related to the color space conversion, both my first script and Deoldify original are working on "color space: RGB24, bit depth: 8, yuv luminance scale: full, matrix: 709"
While the second script is using in input "color space: YUV420P8, bit depth: 8, yuv luminance scale: limited, matrix: 470bg".

yes, and the YUV420P8 is converted to RGB24. The main difference I see is that the source in the second script uses 0-255 as range while the second clip uses 16-235.
What happens if you use Levels to convert your input from 16-235 to 0-255 and adjust the range signaling to 'full' before applying DeOldify?
I also updated the test version with a version where Hybrid will for 'limited' content create code like this:

# changing range from limited to full range
clip = core.resize.Bicubic(clip, range_in_s="limited", range_s="full")
# setting color range to PC (full) range.
clip = core.std.SetFrameProps(clip=clip, _ColorRange=0)
# adjusting color space from YUV420P8 to RGB24 for vsDeOldify
clip = core.resize.Bicubic(clip=clip, format=vs.RGB24, matrix_in_s="470bg", range_s="full")
# adding colors using DeOldify
from vsdeoldify import ddeoldify
clip = ddeoldify(clip=clip, method=0, deoldify_p=[024, 1, 0])
# changing range from full to limited range
clip = core.resize.Bicubic(clip, range_in_s="full", range_s="limited")

which converts limited to full before applying DeOldify.
