Updato S8 firmware issue. Same firmware for different carrier firmware

[dksoni411]

As the title says, I download G950U1 firmware from update.com for XAA/XAC carrier (unlocked carrier). But then I noticed some sprint related system hidden apps in apps settings. So, I decided to download T-Mobile G950U1 firmware. But I was surprised to know both download files were same. I thought it might be the name which is same, So, in order to verify I checked the MD5 of both files and they were same as well.
Here are the links for both firmwares.

XAA

As you can see links for download page are different but if you keep cursor on download button for a few seconds and then copy actuall download links then they are same on both pages (Not sure if this is case with all G950U1 firmwares)

Does anyone know why is so? And I wanted to cross flash from G950w to G950U1 to get rid of carrier bloat and useless apps permanently, that's why I downloaded these firmware. Currently I'm running that mentioned firmware.

This won't help your issue at all but I have an unlocked S8 with the unlocked firmware on ATT and can't get VoLTE, WI-FI Calling, etc. so check to make sure you can get those on unlocked firmware on your carriers network if they're important to you.
