What I experienced was basically no initial brake bite, I thought I thought there was no way I was going to make the corner, but then as the car kind of crested the hill the brakes did a good enough job to slow the car down, but by that time I had already decided to abort the corner. Time stamp should be 13:15 in this video.

Ice mode gives you a hard pedal, as the ABS system is closing the inlet valves into the calipers, and pumping out fluid which was already there. You hit the brake pedal and it doesn't move very much, and feels very hard.
If that's not what you experienced, it could be knockback, where the rotor pushes the pistons back into the caliper. Your initial pedal travel is then spent extracting the pistons to make contact with pad/rotor again. I think this is what you may have experienced based on your description.
I have not had Ice mode once on my '18 SS 1LE. The key is in how you apply the bakes. If you have very grabby pads and you tent to jump on the brake pedal, (instead of applying the 20/80 rule and letting the weight transfer forward) your chances of getting ice mode increase.
And of course loose surfaces can also trigger ice mode too.
