I switched to GSM/WCDMA/LTE auto. I see network type switching between HSPAP, UTMS, and HSDPA. I'm not 100% sure I get LTE at my office, so I will run with this a bit and see what I get.
Currently phone shows 4G icon (not LTE) and I'm getting 92ms/10.1mbps/1mbps.

Obviously with the AT&T branded phone this is a non issue.

I thought the Tmobile radio overlapped with the AT&T ones? I'm limited on my knowledge here, so I'm not sure. Although, based on the below, it looks like the LTE bands overlap?
From AT&T's website, HTC One:
4G-LTE Band 4 and 17
4G HSPA+ HSPA+ with enhanced backhaul
3G - UMTS 850/1900/2100MHz
From T-Mobile's HTC One:
GSM bands 850/900/1800/1900 MHz
UMTS: Band I(2100)
UMTS: Band II(1900)
UMTS: Band IV(1700/2100/AAWS)
UMTS: Band V(850)
LTE Band: 4, 17
Looking around a bit more, looks like I might need to get an AT&T branded LTE phone's IMEI on my account FIRST, before the unlocked T-Mobile one will work. I can't just call in and give them the TMobile IMEI and have them provision it. It HAS to be an AT&T branded one....
