Can you change your trade in estimate?

This may be a dumb question, but here goes...

I bought an 11 yesterday, put in for a trade in kit for an 8 plus. I thought the screen was cracked so filled out the questions accordingly. It estimated it worth about $45. However, I'm an idiot and peeled the screen protector off today (after picking up my new phone) and it was just the screen protector. The screen and the rest of the phone are in perfect condition. So my phone should really be worth $180 for trade in.

Here's my question... will they up the trade in value when they get it? Or will they go with what I put in before and just go with the $45? I would rather just sell it online than send it in and only get $45.

I've never went through the trade in process so I wasn't sure.
