Sorry about the crappy shots, I tried my best...
This is what the screens look like when I'm in the part of my building where I had no problem receiving coverage before, but still deep inside. Confirms PCS. If I go onto the upper floors I get a great band 25 LTE signal.
This is what the screens look like when I'm in the part of my building where I had no service until a couple of months ago. Could still be PCS, not sure how to tell. If it is still PCS, maybe they tweaked the nearest tower a bit so the signal is better. I'm not schooled in the engineering aspect of all of this...I can say that I took these screenshots in the bottom level of a two level parking garage.
