Moshrom covered this back in the day: https://blah-ray.blogspot.com/2018/01/ci...-1988.html
According to him, the PCM 2.0 mono on the now-OOP 2013 Arrow UK 25th Anniversary BD was basically flawless. Judging from the cover art, I'd guess the 2017 Arrow US BD is probably identical.
Unfortunately, the same can't be said for Arrow's 2020 UHD. It sports a PCM 1.0 track instead of the previous 2.0 mono, but Arrow didn't simply re-encode the previous master as 1.0. Below is a spectrogram of the UHD's mono (my own disc), compared against 2002 Spanish Lauren Films DVD (I came across it on the Russian site). I've tried to match the spectrogram settings on Blah-ray.
And for reference, here's Moshrom's spectrogram of the 2013 Arrow BD:
It's clear that Arrow applied a low-pass filter to their UHD beginning at ~16kHz. Corroborating this is professorwho's post on BR:
So, does anyone still have the 2013 UK / 2017 US BD lying around and can capture the theatrical cut's mono track? I suspect it's already in sync with the UHD, since the 2002 Spanish DVD appears to be in sync with UHD.
Thanks!

professorwho Wrote:The PCM mono track sounds pretty good. I did detect some minor noise reduction at points, but it’s nothing too severe to my untrained ears, at least.
So, does anyone still have the 2013 UK / 2017 US BD lying around and can capture the theatrical cut's mono track? I suspect it's already in sync with the UHD, since the 2002 Spanish DVD appears to be in sync with UHD.
