Lumetri Color Dropper Tool

There are too much bugs in the Lumetri Dropper Tool, from the WB to the samplings in the curve.
I don't know what kind of pixel it pick but i everytime i have to repeat the picking until it pick it right.
It seems like the software select the exact pixel of bitrate's noise (i don't know) and choose to confirm whatever color i never selected.
Don't really know what's the matter but create an approximate average of the pixels around the picking, use software of Artificial Intelligence to solve this bug. I don't know but but solve this big problem, i'm going mad with the color correction
