[BotW] revert "contrasty happens before tone mapping"

After futher investigation(?lol), found that shader bd8bb also does color tweaking itself, some part looks very similar to contrasty's saturation (lihe@bestminr.com, also updated credit).
So it's not worthwhile to re-adjust the current contrasty settings, might just revert it before figuring out the game's own color tweaking.
