Add a Posterize node after your Read, set the 'Colors' knob to the value range
of the bit depth you want to check (2^8 for 8-bit, 2^10 for 10-bit, etc.), and
'difference' merge that with your incoming image. Then check which range value
produces the smallest difference.

Subject: [Nuke-users] How to tell bit depth of incoming file
Is there a way to empirically tell the bit depth of a file after Nuke has read
it? I can take a 32 bit file and do a difference with an incoming file to see
that there is a difference but i need to know how many levels of RGB there
actually is in the source file. 8 bit, 10 bit or 12 bit.
Is there a clever way of finding this out i've not been able to work out yet?
Or a way of taking a file and clipping it to 8/10/12 bit to compare against?
many thanks
Paul
