Maya python: find bright spots in light texture in hdri and get the 3d coordinates

This is my first time posting here. I hope someone can guide me to resolve my question.

In Maya, Is there a way to get the 3d coordinates of the bright spots on the Hdri texture on Dome light. And extract those coordinates?

Can we do this in Nuke? In Nuke, can we find the 2d coordinates of the brightest spots of an image and convert to 3d coordinates. Any help on this. Would be incredible!

Thank you!

In NUKE, if you import a 3D scene there, you can use a CurveTool node with the MaxLumaData tool to determine the brightest pixel of the shader's speculars, and a PointsTo3D node to generate 3D axis based on the position of the 2D point.

enter image description here

Camera must be animated, of course.
