Presets with SR

Hi
Just wondering what SR means when it’s attached to the end of a preset.
For example useing Revernce I have Tokyo Studio and then Tokyo Studio (SR).

It is to be used with Dolby surround configuration (I think so).

Thanks.
I looked into the Dolby SR and it says Spectral Recording
I think i’m going into the area of haven’t gor a clue.
