In the end how do you count this ? I guess that's 1 point for white and 1 point for black (+1 if you count the prisoner in).

Under Japanese rules, groups in seki have no points, so it's zero points of territory for black and zero for white. Since black has captured one stone, black comes away from the exchange with one point.

Under Chinese rules, both white and black have one point of territory. Then you treat all of the stones as alive for the purposes of counting the number of stones on the board. So it works out to be the same as Japanese scoring in this case (since white has had one stone removed from the board). However, the unfillable dame could change things.
We don't know who we are; we don't know where we are.
Each of us woke up one moment and here we were in the darkness.
We're nameless things with no memory; no knowledge of what went before,
No understanding of what is now, no knowledge of what will be.
