No, thankfully that hasn't happened to me. Earliest I've ever encountered a Shiny was in Emerald when I ran into a shiny Wurmple in Petalburg Woods while heading to Rustburo less than an hour into the game. Luckily I had plenty of poke'balls and it was an easy capture.
I saw a shiny wurmple the first time i played ruby and it was the first wurmple i ever saw so i thought it was normal then i saw another wurmple and i wanted to kick myself.
