That's great it's carrier unlocked! My S10+ is carrier unlocked but has Verizon boot logo. It's just part of the CSC thing they mention you can flash in Odin but also seems to be linked to the SIM card that's in it nowadays.SM-N960U1 128GB internal memory/6GB RAM and actually AT&T sent me the carrier unlocked version. The sleeve of the box even says "Unlocked by Samsung". But it has AT&T logo when booting up.
Been 4 years since I switched phones. Couldn't get Titanium Backup zip file to flash in TWRP, to copy over all my apps + datea.. Said it completed but nothing actually happened. Now trying to use Migrate.
Using Samsung Switch, most of the apps came over, but not all. Also none of the data and settings. Hoping Migrate will do the job.
I had issues with Titanium doing a proper restore also. I used Migrate and it worked for the most part. What you can try is move all the apps over with Samsung switch or Migrate. I used my same SD card and pointed Titanium to it so that all the apps and data were there, then restore "data only" batch. That worked for me. Seems Titanium has issues restoring APKs on newer versions of Android.
