I keep going back to Deep Darkness - lovely theme with a lot of apps properly skinned as well.
Good mentions in the threads already, like Swift Dark and Euphoria Dark.
I'm using Deep Darkness right now and it's great. Slated MTRL is another good one.
I absolutely love Deep Darkness it is a very extensive theme, basically every UI element is changed. It's pretty dark though, maybe black.
Euphoria is a good theme too. I'm not sure what you think the dark mode in Oxygen OS offers you more than a CM theme. Try Deep Darkness or Playful Flat. They're both dark, but with different accent colors. It's pretty much the same as dark mode with Cyan or Red accent color in Oxygen OS.
I use Deep Darkness by moelle with Umbra icon pack by Vertumus.
I like the theme because it's a dark (but not black) theme that is consistent throughout just about every app (all the ones I've used are fully themed), and is constantly being updated for minor fixes or tweaks to make it better. Only problem I've had with it was black text on a black background in the hangouts dialer, but the just updated to fix that.
Set my screen to 400 DPI (eh same thing) a while ago. I didn't set up anything too spectacular anyway, but it's good enough for me :P
I'm using Nova Launcher and DEEP DARKNESS CM13 theme. The wallpaper is just Muzei with the Reddit plugin. It took a random one from a selection of hot posts from a few subreddits.

It's this one. Completely free and regularly updated. Oh yeah, it's also pretty beautiful.
Personally, I use Deep Darkness. It's not perfect, but it's been the best I've been able to find so far.
Ofc it has themes support, you do need to pick CM13 ready themes like fe https://play.google.com/store/apps/details?id=com.blissroms.moelle.ddoverhauled
Deep Darkness - Themes as many apps as i could throw at it (and still being updated, as far as I know), and looks very nice, but not as material as my other recommendations.
MaterialUp![£0.85] - I like dark themes, so I didn't end up using it for long, but very pretty and colourful.
BlackStockTheme - I used to use this all the time (along with DarkStockTheme) ~~but I can't find it in the Play Store, so I don't know what happened to it.~~ I've found it, I'm an idiot. I recommend this for amoled phones on a CM based ROM.
Melior NUI - Similar to MaterialUp!, but has a lovely boot animation.
Domination - It used to be the best free theme out there, but it doesn't seem to be updated anymore - only the donate version [£1.39] is..
Swift Black - the most complete/closest to stock black theme I could find for substratum, very nice for amoled screens. The developer is also very active, and pushes out regular updates.
It's a part of my theme, I think. I'm using Deep Darkness.

3 Euphoria Dark CM12 Theme (Dark Blue/Grey)
Deep darkness is my favorite! https://play.google.com/store/apps/details?id=com.blissroms.moelle.ddoverhauled
It's included with this theme: https://play.google.com/store/apps/details?id=com.blissroms.moelle.ddoverhauled but I'm only using the font since the theme is not really my taste.
Personally, I used the Deep Darkness theme for a while and it was pretty good. Always constant updates.

Currently I use Deep Darkness .

There is a theme that you may want to try. It has an installer app so I guess it could qualify as an app as well as a theme. Its called Deep Darkness Overhauled https://play.google.com/store/apps/details?id=com.blissroms.moelle.ddoverhauled&hl=en it themes your apps as well and it looks great , the only problem is some of the notifications can be unreadable due to the color of the text but that's a minor issue for me.
