I believe Apple sent me a Demo iPhone for AppleCare replacement

A couple months ago, I broke my iPhone XR and contacted support in order to get it repaired.

They shipped me a box so I put my iPhone XR in the box and shipped it to them.

(I payed around $150 for the replacement)

After a couple months of using the replacement phone they sent me, I found out that it was a demo phone because when I tried to edit Screen Time, a message that says "Feature not available in this demo." popped up.

I'm pretty sure Apple is not supposed to send demo phones for replacements?... or am I tripping
