Hmmm. You should look at it in motion then; maybe the improvements are there.

Playing back at 1/4 speed is generally okay to see temporal artifacts better while still keeping temporal coherence. You can still detect discontinuities between IDR/i/P/B/b that way.

Testing at a higher CRF, like maybe 28, can also make differences at lot more obvious. Working at a quality where most things look pretty good can make differences much harder to detect.
