I'll. do my best to answer your questions.
On my color Settings window, I have: Settings: North America General Purpose 2, RGB: sRGB IEC61966-2.1.
I don't use Soft proof or know what it is.
Let me know what you want a screen shot and I'll provide.
For specific's, I have a color that I am using in Illustrator. Using color picker, I get a Hex of #ff6e00, and R255 G110 B0.
I entered the Hex #ff6e00 into my website. Looking at where that color should be depicted and using digital color meter, I get R255 G152 B40, a noticable difference from what is shown in Illustrator.
Does this info help?
You probably can't avoid sitting down and fixing this by actually instating CM or in reverse, completely turning it off. Start by checking your monitor settings. If there is any factory profile assigend, simply unassign it and see if it makes a difference. If you have created a custom profile, the opposite would be required - you need to also use it for the proof preview in AI to get consistent results.
