Yes correct. Very simple and repeatable luminosity across multiple papers.

   This does seem like a nice way to go. However, I'd like the option to

I disagree with the general view that ABW doesn't allow split toning. Yes it
doesn't have a split tone control panel,
but in practice you are limited in whatever toning you do by the paper
white, unless you preprint the whole page with a background colour.
So what you get with ABW is a tone from paper white to whatever toning you
select, so often it is effectively the same as a split tone.
For example if you print on premium luster with ABW you effectively get cool
highlights to neutral shadows. I am not convinced you can't replicate most
moderate split tones with ABW.
To get warm highlights and cool shadows you just start with a warm paper,
something like Ultrasmooth and print with a cool tone setting. Same applies
to QTR.

Just my 2c worth.
