Exchange 2013 STD, why won't >1TB databases be unmounted?

Question

Microsoft Exchange

Colleagues, good morning!
I have Exchange 2013 standard, version 15.0.1497.2, latest cumulative.
According to information from the Internet, the Standard version has problems with mounting databases larger than 1TB (it is treated with a key in the registry).
My databases are mounted and there are no keys in the registry, everyone has the same, the 1TB limit is no longer relevant, or did I misunderstand the situation?
DatabaseSize
------------
1.247 TB (1,370,899,873,792 bytes)
531.4 GB (570,559,561,728 bytes)
602.5 GB (646,929,448,960 bytes)
974.9 GB (1,046,764,060,672 bytes)

Answer 1

2013 standard has a limit only on the number of bases per server (5), but not on the size.
