In theory, but in my experience when restoring a backup most apps don’t actually get fully restored, it’s more like a metadata pointer which downloads it from the App Store. But sometimes you’ll actually get your older version of the app from the backup this way. I successfully used this technique to restore an old copy of Slack on my phone for a year after they changed the app logo, purely out of spite. But it doesn’t seem to work consistently, I think it’s dependent on something about the way the app is published which I don’t fully understand.
