I’d encourage separating the “is it worth putting the experimental subjects through the experiment to get the resulting data?” question from the “is it worth the emotional costs of readers becoming aware of the resulting data for them to do so?”
My answer to the second is “YMMV, but it’s worth it for a substantial number of readers.”
My answer to the first is “it depends on the specific experimental protocol, but for a decently designed experiment, probably.”
