Not strictly after 90 days, but Denuvo is usually removed after the peak sales period for a game. It's really at a publisher's discretion when to remove it, as the sales model for Denuvo is that you have to continue paying for it on a subscription basis to keep it active.

This is untrue. Yes Denovo got removed from some games relatively early, but mostly it was long after this "peak sales window" I would have to make a list of how long it took for games, and I am too lazy to even ask AI, but I think it took years in some cases and a lot of community outrage for the devs to remove it, and they did not just remove it after some peak sales window but when the games were actually cracked and the steam forums were flooded with pissed of people who realized pirates had a better experience then actual buyers. THEN they removed it.

So it's more like after they were cracked rather than some time window, sometimes these may have been overlap.

1 year after release is for sure not "peak sales window".
