That topic has been cleared up over and over again. I'm not sure that
repeating the information will improve comprehension, but here's another
short summary:
If by "gamut" you mean a well defined volume of tri-stimulus space, then
no, input devices don't have gamuts. This is due to the nature of
the many-to-one spectral to tri-stimulus transform that they perform
allowing for colors that can be be accurately captured if having
one spectra, but not being accurately captured if they have another.
If by "gamut" you mean that they have limits, then yes, input
devices have limits. Just not of the sort that can be defined by
a volume of tri-stimulus space.
That's it. You can stop wondering if sensors have gamuts.
