S.trifasciata 'Hahnii Marginated'? And the colour does not look too good, perhaps it is just the photo.

golden hahnii maybe?

Looks more like Hahnii Marginata, not Gold Hahnii but it does have paler leaf color. Could be another cultivar. Could be growing conditions. Slowly introduce to more sun. See what the new leaves look like. I have some more paler growing types but doesn't look like yours. Time will tell.
