I think a big challenge I’ve faced in transitioning boogie woogie piano (or blues piano also), is around restructuring grace notes to play up (or down) to the black keys.
I’ve gotten sounds close to what I can make when playing Grace notes from sharps/flats onto the naturals, but there is the physical limitation imposed by the way a piano is built that I cannot quite overcome.
It’s physically impossible to slide a single finger off of a natural (white) key onto a sharp/flat (black) key because it is above the point where the white key rests.
The opposite is not true, when a black key is fully depressed, it is above two white keys, and therefore can be struck with the same finger in a single motion.
There are physical limitations with the way the piano is built and for those reasons the same sound requires a more complex motion. In the case above, what can be played with a single finger in the key of C, requires two fingers in the Key of E flat. There are sounds that simply are impossible to recreate in other keys as a result.
