[Feedback]: Threshold

[jdpnielsen]

Describe the problem

The diff threshold documentation links to interactive diff tool. This tool could really use a little quality of life update:

1. Show if there is any change detected (ie reduce the need for a user to spot a single pixel difference)
2. Show an indicator what the difference in a numerical value are between the two images.

Additional context

An example of my issue:

Is 0.09 enough? Or should i tune it more to reduce false positives here? I have to hunt for a single pixel.
