Samsung isn't a charity. They make engineering decisions based on what will make them money.
Statistically speaking, the hundreds of people interested in running Dolphin on their phone are not a large part of the millions of people who bought Galaxy S6 phones, or are interested in an S7.
Generally speaking, most people who are not interested in running Dolphin on their phones also don't know what a "Vulkan" is.
Adding driver support for things is not free; it costs developer time, and developers are not low-wage jobs.
Samsung is not likely to go back and add major new features that only very few people would even notice, for a phone they won't even be selling 3 months from now. Maybe they will! But I wouldn't take "Apple did it" as a benchmark of likelihood. The benchmark is "will it make Samsung money?" And the answer is "probably not."
