WatchOS 7 DNS Profile

I am trying to install a DNS profile on my Apple Watch. I cannot install a normal DNS profile that would be used (and works) on my iPhone on my watch. After setting

Code Block 
<key>TargetDeviceType</key>
  <integer>2</integer>

in the profile pasted below, the system says:

Invalid Device

This profile is not valid for Watch.

My question is this: Is the profile being installed/configured incorrectly, or does WatchOS 7 not contain the Encrypted DNS that all of the other platforms now have.

The profile 'dns.mobileconfig' is pasted below.
