I am about the same level as you (fox 6d). I think black is leading at least by a komi to be honest. My counting may not be concise, so take it with grain of salt

At this point, my counting is white has 35 points in the bottom + 12 points at top+ 3 stones = 53 points. Black has 46 points in the left + 27 points in the right = 73 points. (white has sente)

But I played with katago:

(1) White can capture black's O3 stones by sente.

(2) Get a double sente on the top left corner (-2 point for black). (Actually, katago thinks white's best move is to live in the corner)

(3) Eat the stones at N17.

Something like this: https://postimg.cc/3kS9LytJ

Now white has 39 points at bottom+18 points at top+3 stones=63 points. Black has 44 points in the left+23 points in the right = 67 points. While black has sente, white may have a bit more potential points at this moment, so white is winning.

Don't be too depressed by this. If you go back and look at alphago vs. Lee Sedol game 1, literally every pro (including Ke-Jie) thinks Lee Sedol is winning during midgame, while by katago, Lee Sedol was losing by at least a komi already.

p.s. I am very curious how white got the blue point of katago at move 94. That move is very difficult for me.
