It sounds like it's doing everything right. Are you following my instructions here? https://www.damiensymonds.net/cal_S5P_mac.html
The "Target" of 120 is not important.
What's important is the "Current" number. What does yours say?
You have to stop getting new prints! You just need to match the prints you already have.
PLUS, you need to have more photos than just this one. You need a range of photos.

Yes, you absolutely should be making your screen darker to match your print. Is that what you've done?
