Short description of error
Although we have 5 pixels of Outline Width options for the theme, the selection outline only has only two thicknesses available.

Exact steps for others to reproduce the error

In the Interface - Line Width preference set to Auto or Thin
In the Themes - 3D Viewport - Outline Width try test all available pixels (1-5px)
1px and 2px show up the same, and 3px, 4px, and 5px show up the same effectively giving a choice of only two line thicknesses.
In the Interface - Line Width preference set to Thick
The line thickness is now constant and doesn't change with the theme setting, and is slightly thicker than what 3, 4, and 5px would give.

This is a limitation of the current algorithm used to detect the outlines. It does not scale well to higher outline width so it has a hard cap.

Fixing this would mean changing the algorithm.

Some inspiration for someone to pick this up (or future me):
