Yea, I can confirm there is no way to check *through looking at the model files

Blender drops this little header at the top of an OBJ file, which is commented out
When converted to a .MDL / necessary valve formats, there is no appearance of the header anywhere.
When exporting into an SMD then into .MDL the SMD (from blender) does not include a header at all, this is likely similar from other software (check it yourself (HxD) for other software if you really need reassurance).
