There is no command to do that. I would suggest to enable diffserv examinition, configure every codepoint to match the right QP (qosprofile) and see which qosprofiles are hit using 'show qosprofile '.

i also suggest using wireshark (free) and set a basic filter such as
ip.addr == (ipaddress of the pc reviewing)
maybe set up a port mirror to capture the packets for review

There is no CLI to check the incoming DSCP value.

The best way is to mirror ingressing packets and analyze them through the wireshark.

You can check if the packets are egressing in the correct queue with the command below:

show ports qosmonitor
