Soloing, you sound like someone who is into Jazz, Smooth or otherwise. Tonally, you sound like a very good player favoring the back pickup on an active bass. Barring a new technology in bass guitars, I don't think there any really dramatic new sounds in our favorite instrument. I remember Jaco came out, and even accomplished young bassists were trying to figure out how he got his sound. I remember buying my first fretless and panning to the bridge pickup, and I was like "Oh, that's how he does it!"
I am a good bit older than you. I took up Gospel when the little groups I played in petered out, and I had an opportunity to play for a university choir and a church. I honestly had never seriously listened to Gospel, and I just used my Funk chops. I was more than ten years in before I really began appreciate Gospel, and listen to Gospel bassists as a discrete genre. I am now seriously studying because I just tired of holes in my knowledge.
I think guys coming to Gospel from different sorts of Pop and Jazz is very common except players who grow up COGIC or a related denomination. Gospel has always had a ton of outside influence. I actually like Quartet, and Old School Gospel. I post a lot of clips on my YouTube channel, but my level of play is far below yours.
