Here's my take on kinetic/katastematic pleasures. I don't give any guarantees whether this is a sound take but you can take my take as a takeaway and feed your thoughts with it, if you wish burninglights.
Katastematic pleasure is an embedded phenomenon in a sensory processing unit. In other words, everything that is alive, has senses and a brain (or the corresponding organ) capable of translating sensory inputs into experiences, is equipped with katastematic pleasure at birth. This pleasure is, simply put, background noise to life.
As such, katastematic pleasure has nothing to do with intensity, location and duration. These can be descriptors of kinetic pleasures. If one really wants to apply these descriptors to human katastematic pleasure, they would look something like this:
intensity: subjective and unquantifiable
location: somewhere between one's ears
duration: lifespan
If a person has difficulties recognizing this background noise as a pleasure, or worse mistakes it for pain, their quality of life suffers and their lives turn into never-ending battle against ghosts that are not on there.
Kinetic pleasures are everything else, including gratitude you were wondering about.
