I agree those test mean nothing with out some context, even then a laser temp gun would give a more accurate readings at each tread block for comparison.
Are they pics of the same tyre even?
Front tyre will generally be hotter than rear due to wheel alignment and steering force.
Pics are in different locations and very different road temps.
Which one do you think is happier? You don't make that clear.
To me the lower pressure pic looks far more even, the higher one is much hotter on inside edge
