More likely the low level distortion created in the analog audio path typically occurring with the stronger signals. That distortion is therefore multiples of the fundamental and the human hearing will allow the higher frequency components to be dominate, often described as masking effect thus perceived to be louder. It is the combination of F + Fx2 + Fx3 and etc. This is usually the result of the dither component of digitally processed signals. A 2nd point with stronger signals the background noise, always higher in frequency content, will be suppressed thus the timbre of the signal will change as the reference point of hearing changes.
