Different frequency bands between AT&T/T-Mobile/Rogers/Telus versions of HTC One M9

I've tried to dig up the info as to what the differences are in terms of frequency bands available for each of the different GSM versions of the HTC One M9. This is what I came up with from the carrier websites:

AT&T
• UMTS: I/II/ V
• LTE: 2/3/4/5/7/12/17/29

T-Mobile
• UMTS: I/II/IV/V
• LTE : 2/3/4/7/12/17

Rogers
• UMTS: I/II/IV/V
• LTE: 2/3/4/5/7/12/13/17/29/30

Telus
• UMTS: I/II/V
• LTE : 1/2/4/5/7/13/17

Does anyone know if this is indeed accurate? Does someone have the proper info? Thanks.
