Should I verify installer file PGP hash?

Let's say that I'll download an installer for a program on Windows and the publisher has released PGP Signature for the file.

The installer file does not have any code signing certificates.

If I connect to the publisher's website with https and check that the URL is correct, do you think I should still verify the hash?

From what I understand, the purpose of this is to make sure that the download was not intercepted by a third party and to make sure that I downloaded the correct file.

Is that still a threat even if I connect with https and check the URL?
