TFC would be categorized as a "Directors/Producers Revision" like the Criterion releases of The Last Emperor (2.00:1 hatchet job by the cinematographer).

However, another notable example of poor/DNR'd transfers would be the 2008 BD of Patton. Luckly, Fox (quietly with little fanfare) released a new transfer without the DNR pass applied, kinda like the June 2015 BD+digital copy release of Terminator 2. So it seems some studios ether are "trying" to get with it now with 4k BDs coming up, or they got someone different at the digital transfers department who decided not to apply any smearing filters to new BD pressings.

Here's hoping this new hog wild "30th-Anniversary-Special-Ultimate-Collectors-Premere-Limited to 1985 copies" edition of the BBTF trilogy will have transfers of the films without the DNR and processing passes, but who knows. Regardless, BTTF: The Animated Series, may make this more worth getting since (despite its wonky drawings and such) it hasn't seen the light of day at all outside of TV airings and VHS bootlegs.
