Those SIGGRAPH talks, OCIO and Jeremy Selan's http://cinematiccolor.com have been a touchstone a while :) Thank you so much for the filmicgames link, that's exactly what I was curious about.

In return maybe I can offer the Academy's linear-to-display reference rendering transform, which is intended to replace the myriad of tonemapping LUTs currently used for film: https://github.com/ampas/aces-dev/blob/master/transforms/ctl...
