Diffusion Filtration in "Deliverence"

The early scenes look like a mix of different techniques, depending on the scene: flashed negative, low-contrast and double-fog filters. Plus most of the picture was shot using anamorphic zoom lenses, which contribute to reduce the contrast and overall sharpness. The second half of the film still has some diffusion effects, but less heavier than the first half.
Check any other film shot by DP Vilmos Zsigmond from "McCabe and Mrs. Miller" to "Heaven's Gate" to find a similar approach to contrast and diffusion.

I know that they wanted to shoot the movie under overcast skies, so using the mild Double-Fog or Low-Con might have been an attempt to get the sunny shots to match the lower-contrast look of the overcast shots.

Breifly, from what I recall they used a B&W print as a mask when printing so that they achieved something similiar to a present-day bleach bypass. So that the B&W print kept light from making the colors seem super saturated, by blocking the print negative frm getting dense. However, the B&W print mask would be clear where there was white light so maybe that was resulting in making the highlights bloom as in these shots.

According to the articles I've read, they created a b&w dupe negative from the color negative and combined them in two passes to make a desaturated printing negative using the CRI process.
What you're thinking of is the day-for-night sequence, where they made a b&w hi-con dupe of daytime scenes to create a hold-out matte of the bright sky, which they then used in an optical printer to create a dupe where the sky was nearly blacked-out.
Those shots I posted clearly show the effects of a fog-type filter like a Double-Fog or Low-Con.
