No.

Dirt happens.  Phones don't magically get dirty less than lenses of high end cameras.  In fact, the opposite is true.  Even a semi-serious camera lens has a cap or hood.  This is a simple mechanical barrier that minimizes dirt accumulation when the lens is not in use.

Your question is also based on a false premise:

<blockquote>professional cameras with lenses that require constant replacement and care</blockquote>

Camera lenses for professional use don't require "constant replacement", and no more care than any other lens, <i>if you want good optical quality</i>.  They generally attract less dirt due to being capped when not in use than smart phone lenses.  The reason it may appear that smart phone lenses don't need any care is because the users aren't expecting the same photographic quality, and largely don't care nor want to be bothered with the maintenance.
