You are comparing two different things. Lockdowns, mask wearing, and other mitigations seek to drive down the number of infections. The death rate (IFR/CFR) is the relationship between the number of infections and the number of fatalities, so no one should expect lockdowns to change the death rate (up until health care runs out of beds/staff).
