WoW Freakz spell link: https://www.wow-freakz.com/spells.php?spell=212817&name=fiery-demise
Bug description: Fiery Brand's trait is supposed to increase the fire (and chaos) damage taken by the target from sources coming from the demon hunter. This currently does not affect either Kil'Jaeden's Burning Wish nor Archimonde's Hatred Reborn.

Those 2 trinkets dont get any increase from anything , no buff in the game period. Fiery Demise works just fine with the rest of the demon hunter’s fire spells.

I believe they do get increased by sources of % increased critical damage and % increased damage taken.

Disclaimer: I coudnt find a source more reliable saying whether they should or should not get their damage increased.

here's a clip of a guy doing 1.1M with KJ in 7.2 before legendaries were raised to 970.

and here he is only doing 830k per target with it

This one gave me a bit of trouble as far as finding correct proof goes, but here's what I came up with. I cannot rely on your Source 100% due to it being from a newer version of the game - 7.3.2.
This is all very volatile data, as it isn't from Blizzard directly - but that's the best I could find, even this took me ~3 hours.
So, first of all KJBW should scale only with % increased critical damage buffs (Pyretic Incantation, Burning Gaze) and % increased damage taken debuffs (Colossus Smash). As can be seen in the picture, it does not scale with Artifact Traits which is what Fiery Demise is.
Moving on to AHR however, the best proof I could find was here, in the 2nd comment you can see the guy discussing the damage part of the trinket: "Damaging part of the use effect is a bit disappointing. Yes it can hit big time on single target (from 1 mil to 2.3 mil with Fiery Brand or any other debuff that increases fire damage)". Another potential proof for this can be found here, by scrolling down to the Legendaries tab.
TL;DR: KJBW shouldn't scale with Fiery Demise, AHR should.

EDIT 22.1.2019:
Upon further inspection, I've concluded that KJBW does actually scale with Fiery Demise as can be seen here by comparing the 1st usage of the trinket (at around 30s in, with Fiery Demise) with every other usage after that (without Fiery Demise).
