Of course it's what they're telling us, they designed the GPU. RT improvements almost certainly need to be accounted for in game code, the RT cores themselves definitely do now have increased capability relative to Ampere.
Also, a node shrink ≠ the improved power circuitry for spikes. The
massive extra cache, the 4x improvement in tensor flops which outstrips the increase in tensor cores x clock speed, the 3x faster OFA..
Here's the Ada vs Ampere block Diagram, note the capabilities in the RT cores and the L0 i-cache.

You can choose to see no improvement if you want, but this is factually not a die shrunk Ampere despite how the swing of reactions go, it may share the vast majority or architectural design, but there are indisputable additions and differences, ergo in an absolute sense, not a die shrunk Ampere.
