Deoldify Vapoursynth filter

[Dan64]

I have the problem.

Steps to reproduce it.

1) Import the attached image
2) Color->Tewak->Saturation=0
3) Preview

The generated script is

# Imports
import vapoursynth as vs
# getting Vapoursynth core
import sys
import os
core = vs.core
# Import scripts folder
scriptPath = 'D:/Programs/Hybrid/64bit/vsscripts'
sys.path.insert(0, os.path.abspath(scriptPath))
# Loading Plugins
core.std.LoadPlugin(path="D:/Programs/Hybrid/64bit/vsfilters/Support/fmtconv.dll")
core.std.LoadPlugin(path="D:/Programs/Hybrid/64bit/vsfilters/Support/libimwri.dll")
# Import scripts
import adjust
# source: 'D:/PProjects/vs-deoldify_dev/TestCOL1.jpg'
# current color space: YUV420P8, bit depth: 8, resolution: 1280x1490, fps: 25, scanorder: progressive, yuv luminance scale: full, matrix: 709
# Loading D:\PProjects\vs-deoldify_dev\TestCOL1.jpg using vsImageReader
clip = core.imwri.Read(["D:/PProjects/vs-deoldify_dev/TestCOL1.jpg"])
clip = core.std.Loop(clip=clip, times=100)
frame = clip.get_frame(0)
# Setting detected color matrix (709).
clip = core.std.SetFrameProps(clip, _Matrix=1)
# Setting color transfer (2020), if it is not set.
if '_Transfer' not in frame.props or not frame.props['_Transfer']:
  clip = core.std.SetFrameProps(clip, _Transfer=15)
# Setting color primaries info (to 2020), if it is not set.
if '_Primaries' not in frame.props or not frame.props['_Primaries']:
  clip = core.std.SetFrameProps(clip, _Primaries=9)
# Setting color range to PC (full) range.
clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=0)
# making sure frame rate is set to 25
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
clip = core.std.SetFrameProp(clip=clip, prop="_FieldBased", intval=0) # progressive
# Color Adjustment
clip = adjust.Tweak(clip=clip, hue=0.00, sat=0.00, cont=1.00, coring=True)
# Resizing using fmtconv - spline36
clip = core.fmtc.resample(clip=clip, kernel="spline36", w=1280, h=1488, interlaced=False, interlacedd=False) # resolution 1280x1488 before YUV420P8 after YUV420P16
# adjusting output color from: YUV420P16 to YUV420P10 for x265Model
clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P10, range_s="full", dither_type="error_diffusion")
# set output frame rate to 25fps (progressive)
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# Output
clip.set_output()

And in preview I get
