I'm not sure why an entropy pool would not be considered "truly random"
by any of the three criteria you cited.  If there is insufficient
physically-generated entropy (such as on an appliance with no hard
drives, no user timing input, and all other sources observable or
predictable) then the process is not applicable - it cannot create
entropy by magic.

But by what criteria would it fail to be truly random (albeit at a much
lower rate than dedicated hardware) on an uncompromised user desktop?

The link you cite above is an example of the extra hardware that most
people don't have.

The link you cite above isn't a truly random number generator.
