If the MCU is protected by "read-out protection" (RDP 1 or 2) then you cannot read the internal flash via debugger interface with any tool.
But you can run the firmware to tell you its own version.
Is this useful info?

If the part is readable, download and compare, or place a version tag that is clearly visable in the front of the device
Say unused vectors.
