Remember too that guitar amps, in general, have a pretty good amount of compression. If your running your amp at a given level, and then step on a boost pedal, with let’s say 20dB boost, your amp output does not jump 20dB in output intensity level. Instead it saturates more, and has some degree of output boost, but your certainly not getting a linear into to output effect.
As such, while your not getting anything like a hard limiter, unless you set it up like that, that typical patch isn’t likely to have massive spikes in levels, even if you step on some stomp boxes in your signal chain etc
