Nothing. I'm talking about screen-to-transparency matching, which I think I
was pretty clear about.

That may be true, but it doesn't change the fact the I still have to produce
screen-to-transparency matches daily!

Is there a replacement for it? As far as I understand it, this is basically
still the current spec and the standard viewing conditions haven't really
changed. ISO 12646 talks more specifically about matching screen to viewing
booth and the changes necessary to achieve that, but it largely refers to
3664 as the base-line viewing conditions.

Yes, but again I'm talking about transparencies and when you control the
luminance of the light box (i.e. lower it enough so it matches the screen),
the image looks too dark.
