Yes the apk signature is authentic, but there are parts of the apk that are not protected by the signature which can and obviously have been modified here.

Check the apk with apksigner using the following command:

apksigner verify --verbose --print-certs

You will get these warnings that a bunch of files are not protected by the signature. That's why I personally won't use it. Yes the Samsung main files are authentic, but something's been changed in the files that aren't protected by the signature to make it work. It's modified.
