Perplexity.ai rebuked me for asking about this:
"
The idea that setting the amp model saturation option to
Ideal means fewer settings change when switching between amp models is
not supported by available official or community information. The saturation switch modes-Off, Ideal, and Authentic-primarily affect the saturation character and output volume of the amp model, with Ideal providing a hotter, more aggressive saturation and Authentic offering a more realistic volume level with saturation engaged

There is no indication in the Fractal Audio forums or official documentation that choosing Ideal saturation reduces the number of other amp parameters that change when switching amp models. In fact, the Fractal Audio Blocks Guide explains that when you change the amp type, various parameters automatically reset to starting values appropriate for that amp to ensure accuracy and tonal correctness
5. This behavior is independent of the saturation mode.
The saturation setting affects tone and volume but does not control or limit parameter changes triggered by switching amp models. Users on the forums discuss saturation mostly in terms of tonal impact and volume differences, not parameter stability across amp changes

For authoritative details, see the Fractal Audio Blocks Guide PDF (especially the Saturation Switch section)
5 and relevant forum threads such as "Saturation switch settings????"
2 and "When should I use the saturation controls?"

Still, I hope you are correct because it would be one more way to have amp settings persist a bit, without opening up fractool and using "manage amps", which lately seems to take several minutes to "warm up" before communicating properly with my Axe Fx II MK 1 unit (sadly all I have).
