The thermal images are in a special JPEG format that stores the ratiometric thermal data for each pixel, so reprocessing the image with different thermal scales and ranges is possible.
I reduced the thermal range represented by the color scale to show any thermal gradients across the cells, and still no sign of the dents, so I don't think it effects the cell performance at least in the limited samples I have.
The images is really 19,200 individual IR thermometers, so there is a lot of data there.
