Secret AMOLED appearance option in Discord
How to get it:
Go to appearance
Click dark mode 9 times
An option named AMOLED will appear, click it
You will get reloaded and it will give you an even darker mode
If you want to go back to normal, just click the mode you want to go back to (light or dark), reload discord and boom, you are back to your normal discord mode that you use.
Enjoy!
