I'm assuming our cars have trunk torsion springs (I m not at home otherwise I would check). Assuming so, and that the springs are different for models with spoilers, it could explain the difference you felt. More weight = stronger springs.
The SS-1LE spoiler is really light, so I would be a little surprised if Chevy used different springs on cars with that option. That said, my LT1 was optioned with a CFM blade spoiler from factory (same shape as the SS-1LE spoiler) and my trunk does close with an excessive amount of force; so much so that I usually lower the trunk by hand until it's within 1-2" of being closed, then let go.
Storytime: I owned a 2006 WRX STI over 15 years ago. It had a huge oem trunk spoiler. I removed it once for fun, and the trunk could have doubled as a trebuchet when pulling the release.
Edit: I looked at my trunk last night and didn't see any torsion springs, but a lot is covered by trim panels. Perhaps the hinges/shocks are doing all the work and there's no torsion springs.
