As I promises I've test it with your settings.
That's what the majority of users (common desktops or laptops) will see:
Considering that:
1. Our tastes differ when it comes to colors;
2. It's difficult (for me) to make the plugin highly customizable for all kind of particular users.
3. I'm interested more in the functionality of the plugin than how it look under many different circumstances.
I suggest you to make and share your plugin variant (let's say 4.6.DMA or 4.6.DARK or whatever) dedicated for peoples like you with huge monitor(s) and a dark theme installed.
You've started already and it is a good start. Unfortunately, you'll have to maintain it.
You could post it in the same place with mine to be more easy to find.
