There's really no reason why BT wouldn't do somewhere that is clearly viable (city centre) and has credible competition.
Unfortunately, being in a city centre is no automatic indicator of commercial viability. Edit: Nor is competition from Virgin a sign of viability either: BDUK's presentations say that there were 2.7million premises which have VM as a superfast option, but not Openreach.
In this case, cab 191 seems to handle only 3 postcodes, and 2 of them are partly served by other cabinets.
It is likely that the number of lines makes it unviable - not enough business to get a power supply installed.
