Phone boot splash screen

Novice II

I'm just curious if I should be seeing a visible phone boot splash screen after swapping service. Whenever I reboot my phone I still see the T-Mobile shutdown and boot startup screens. I have confirmed I'm on the visible Network my phone number was ported over properly and text messaging and data are on the visible/Verizon network.  This is obviously not a big deal but I hate T-Mobile so much that I would love to erase all aspects of them from my phone LOL
