Not so suprise result is odd... But basicaly, you'll see darker colors than original. Effect even worse (a lot darker) with HDR data.
If you haven't, read the pdf document i've put with the filter, i've tried to explain how things work (at least, what i've understood).
Maybe it will help you.
"Borked" effectively means "broken". It's probably slang.
These definitions possibly come across as being somewhat insulting, but that definitely wasn't my intention.

What I'm failing to understand (I seem to be doing a bit of that lately) is how the intermittent XYZ colorspace matters when I shouldn't be seeing it. The screenshots were taken from the output of a script using this (2020 to 601).

ConvertYUVtoXYZ(Color=1).ConvertXYZtoYUV(Color=3, pColor=1, OutputMode=2)

Shouldn't I be seeing a fairly similar result to this (the expected result)?

ConvertYUVtoLinearRGB(Color=1).ConvertLinearRGBtoYUV(Color=3, OutputMode=2)

Thanks.
