Man,.. why post the whole script, each time,..

Looking at you correct way:

# Source: 'TestClipSingerBW.mp4'
# Current color space: YUV420P8, bit depth: 8, resolution: 480x360, frame rate: 25fps, scanorder: progressive, yuv luminance scale: limited, matrix: 470bg
# Loading TestClipSingerBW.mp4 using LWLibavSource
clip = core.lsmas.LWLibavSource(source="TestClipSingerBW.mp4", format="YUV420P8", stream_index=0, cache=0, fpsnum=25, prefer_hw=0)

load the source

clip = core.resize.Bicubic(clip=clip, matrix_in_s="470bg", matrix_s="709", range_in=0, range=0)

converts '470bg' to '709'

# changing range from limited to full range
clip = core.resize.Bicubic(clip, range_in_s="limited", range_s="full")

remaps 16-235 to 0-255

clip = core.std.Loop(clip=clip[185], times=257)

repeats frame 187, 257 times, no clue why you do that,...

# setting color range to TV (limited) range.
clip = core.std.SetFrameProps(clip=clip, _ColorRange=1)

this tells Hybrid the source is limted, this seems wrong, since you just converted it to 'full' beforehand.

# setting color range to PC (full) range.
clip = core.std.SetFrameProps(clip=clip, _ColorRange=0)

So now you change set the color range to 'full' again

# adjusting color space from YUV420P8 to RGB24 for vsDeOldify
clip = core.resize.Bicubic(clip=clip, format=vs.RGB24, matrix_in_s="709", range_s="full", dither_type="error_diffusion")
# adding colors using DeOldify
from vsdeoldify import ddeoldify
clip = ddeoldify(clip=clip, method=0, deoldify_p=[0, 24, 1, 0])

now you apply DeOldify

So all in all up to this point (ignoring the frame duplication thing) you made sure that if YUV content was present it is converted to matrix bt709 and luma range full before converted to RGB and fed to DeOldify.

# adjusting output color from: RGB24 to YUV420P10 for x265Model
clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P8, matrix_s="709", range_s="full")
# set output frame rate to 25fps (progressive)
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# output
clip.set_output()

now you output full range.

Would have been way easier if you had spend the time to write down a few sentences of what you did or indented to do.

I write a test version which will make sure DeOldify is fed with 'bt709' and 'full' but will revert to the original values afterwards.
If you want 'bt709' and 'full' output, you should use Levels to convert the levels and ColorMatrix to change the matrix before feeding the source to DeOldify.
