I have Gala and Galarina both planted this year. The Gala shows minor signs of CAR but the Galarina is clean. Given their short history that probably doesn't mean a lot. I've had trees severally affected one year and nary a blemish the next.
My experience reflects that of gunfun13. Galarina has always been clean for us, depending on the year Gala can show some "spotting" but not as bad as say Honeycrisp or Goldrush.
