ELE on Nexus does not touch exteriors at all, no such module uploaded as of yet. The only thing affected in the exteriors are the light bulbs, which has no exterior or interior restriction.
I have a Lite version of the ELE-Weathers module lying around and I've had some positive feedback on it, and it will be released with the next ELE - Lite update.
ELE - Weathers is the only ELE module to affect exterior lighting.
ELE-Lite v0.9.5 - Only Interior version will be uploaded soon, later today.
Relighting Skyrim only adjusts light bulbs and not the ambience lighting/none light bulb lighting, which is the point of it, minimal amount of edits and only edits done to cell placed light bulbs to have the greatest compatability with as many mods as possible, both technically and visually.
By the way, ELE is the "byproduct" your speaking off and ELFX - Enhancer can also be considered the "byproduct", you can even use RLO with some TES5EDIT adjustments to the RLO files.
That is the beauty with Relighting Skyrim if an interior lighting mod looks good with the vanilla game, it looks good with Relighting Skyrim.
Why the light bulb colors in the exteriors looked cooler/desaturated is because of the way the exterior imagespaces/weather imagespaces was setup by Bethesda.
They desaturate the colors by adding a grey-ish color filter and high contrast values and then for some reason they upped the saturation, which didn't do squat, I don't thik they knew what they wanted in terms of visual when they assigned these values to the imagespaces.
That affects the light bulbs, well everything in the visuals, making it a ugly looking night scene with pitch black shadows and mid-tones and no colors at all, or a very small amount of it anyway.
