Just to answer this for you since no one really did.
The difference is in the side chain/detector circuit for the compressor.
So a stereo linked compressor takes the signal from the L and R channels and usually combines them down to mono and this is then used to detect when the compressor should compressor as set by the threshold.
A dual mono means each channel is totally independent not use in terms of level, attack times, release times, threshold, but also sidechain/detecor. Each channel listens to its own side chain so they compress completely independently from one another.
Some compressors take this up a notch(API 2500 for instance) and has a blend control so you can actually either be 100% fully unlinked or you can mix it down all the way to unlinked. Kind of cool that way.
As others have stated if it's a stereo link this can feel like it collapes the imaging a bit as if somehting really loud is on the left its going to compressor both L/R signals.
A dual mono would just clamp down on the L which can make the stereo image shift.
summing sidechains to mono causes major m/s issues like original gssl clones.
non-linked detectors cause changing and blurring of the stereo image.
On most units like SSL bus and better plugs like Presswerk and Kotelnikov, there are separate L and R detectors and the compressor chooses the higher one. Of course this lets the channels modulate each other, which you may or may not want.
I don’t know how the Daking FET III stereo knob works with summing the sidechains but Kotelnikov never unlinks the detectors

That is true!
