This PG https://www.babylonjs-playground.com/#H6Q4X3#0 reads an individual pixel by

loading image into a dynamicTexture lines 20 to 31

picking a point on the mesh lines 80 to 83

and the important one getting the color at that point lines 42 to 51

Using code from Pixel manipulation with canvas - Web APIs | MDN

Hope this is what you are after.
