"Camera-Matching Profiles" are only available for Raw images, and furthermore they are not provided for every camera type. Looking at your screenshot it would appear you have a non-raw file selected, so try selecting a raw file to see if there are camera-matching profiles available for that.
This class of hardware profile has always been available for some camera models (especially so, or sooner so, with the most popular camera brands), but not available for others.
Depending on which camera took a particular photo, (edit: as Jim says, Raw photo is understood here) you can see a different list. In the case of a non-directly-supported camera model (imported as generic DNG) there may be no profile choice other than the "embedded" profile which this DNG itself contains.
Even though a standard profile name such as "Adobe Color" or "Adobe Standard" tends to always be available, behind the scenes this denotes a different Adobe Color or Adobe Standard profile per camera model. The same thing is true for camera matching profiles: even though the same camera matching profile name might appear, this really denotes a different such profile per model. Which may, or may not, be present.
