In spite of the disdain shown by many to presets or styles, I've bought a fair number over the years for similar reasons.
Not because I wasn't already using all the sliders etc, (I've also paid for several online tutorials, and watched many Youtube videos, so was aware of how to use them) but because it was useful to see how particular effects were being achieved from which combinations of adjustments.
Unfortunately, some. like the ones from Ted Forbes (which I was particularly keen to see), were completely useless because they use LUTS and the adjustments being made are hidden.
Recently, I was struggling with a photograph from. misty day of helicopter lowering someone onto a ship at sea. Everything was almost the same tone and I was struggling to get it to look the way I wanted. Eventually, I ran some styles (presets) acoss it and found one that gave just the right amount of tonal separation without losing the feel of the day..
Looking at the settings used by the Style gave me an insight into how it had done this, As I continued with the processing I became aware of which settings removed the tonal separation it had added, and eventually got something close to what I was wanting. I would have probably got there eventually, but using the style speeded up the process.
I don't do this very often, but it's a useful tool to have available, and of course LR has its own set of profiles and presets that you can try out (but the profiles don't show any adjustments so limited as a learning tool)
