My opinion of D/s play in the hobby is that you can lightly explore it, but it is hard to really explore it. I don't even try to. To really explore, you have to develop a relationship, get to know and trust each other, the sub has to especially trust the Dom. You have to talk about limits, the Dom has to understand which ones are soft and the hard ones, and the ones in between. As you play those limits and other interests will evolve - if you are truly open minded. I have many interests now that I did not have a few years ago. There has to be a lot of communication involved.
The hobby revolves around limited interaction before meeting and relatively short meetings. A D/s scene takes time. It takes time to prepare and to play out. Unless the Dom (assuming in this instance that he is the male hobbiest) wants to pay for multi-hour sessions, I don't think this is realistic. And I doubt may providers are going to be restrained in the first few meetings.
Exploring light kink is probably more realistic in the hobby. That probably happens a good bit. But a lot of people think deep throat, being called slut or daddy, spankings, PSE meetings are kinky. To me those are not really kinky
But I also think that "kinky" is a marketing word by many providers. It is used in ads, but not a lot of kinky play actually happens. I know of one that has "Kinky" in her name, but I have never seen anything kinky in her reviews.
I'm sure there are exceptions, but I bet they are the exception. I hope that was what you were looking for. Just my opinion, it is only worth what you paid for it
