Seki

B1 and B3 make the corner a seki and nullify White's territory (6 points after White playing inside).

Is it really seki?

Later, W1 can capture two stones, but then has to give way after B4 - leading ultimately to the same score as the seki.

Result after follow-up

4 points for each side - the net is still zero. White can use W1-W3 above and a as two ko threats for small ko fights.
