So kcachegrind and any distributions' package would also need written persmission from OmniTI Computer Consulting.

No, because dprof2calltree is modified 4-Clause BSD.

It fails the "desert island test" because

1. Any mention of the features or use of this software requires
user-facing display of the text "This product includes software
developed by OmniTI Computer Consulting".

2. OmniTI Computer Consulting's name cannot be used to "without specific
prior written permission"

The desert island does not have the paper snailmail service required to
fulfil #2 (4th clause of the license).
