Yeah, magenta was almost the 90s equivalent of teal/orange. Video transfers, while more neutral and balanced in terms of color palettes and contrast than what we see today, were also often plagued with this magenta boosting - for example, I noticed the weird magenta/purple tinge on A New Hope
E even back then (especially after looking at Treadwell's side-by-sides with the GOUT LD). The first DVD of Ghostbusters, some transfers of Jurassic Park (I think the DVD more so than the VHS/LD?) and most transfers of Phantom Menace look that way too. From what I remember, even the VHS/LD transfer of Beauty and the Beast that I and others always held up as looking better than the DVD/BD, had too much pink in it. I'm sure there are plenty of other 90s transfers with the same tendencies. And it wasn't just theatrical films - if you compare the original video masters of Star Trek: The Next Generation with the HD remasters, you can definitely see that the Enterprise bridge, Picard and Riker's uniforms, and other stuff have this pink/magenta tinge to them in the SD originals.
Was it done to get the colors to look good on that generation of CRTs? I do remember that the colors of these transfers did look good on my family's late-90s-vintage tube TV back in the day, it probably wasn't as glaring before LCD flat screens, but even then I think I did notice more purple/magenta (especially with stuff where I'd seen previous video releases, like ANH or Ghostbusters). I've said this before - just because the teal/orange revisionism on modern remasters is wrong, doesn't mean that the colors on the previous masters of those same movies were any more accurate to how they looked in theaters.
And BTW, earlier in this thread you said you thought PILF-2187 comes the closest to the theatrical timing. I beg to differ; I watched MrBrown's samples, and there are parts which have little to no blue tinting at all, where the film cells have a definite blue cast - for example, the hospital chase:
