[FreeU] Effects seems not obvious

I tried several shots to evaluate the FreeU functionality. But I couldn't see any improvements with FreeU. Is this my configuration issue or it's a common case?
Below are comparing results:

1. "mother dragon hugging a baby dragon", Extreme Speed mode, sampler steps: 8

Without FreeU

With FreeU

2. "a baby dragon stop on a tree, tropical forest", Extreme Speed mode, sampler steps: 4

Without FreeU

With FreeU
