Your SCOBY looks fine.
If you're worried about the finished KT, taste it and smell it.
If it looks fine, smells fine, and tastes fine, then it is fine.
If there's anything wrong with it your nose will tell you before it makes it to your mouth.
Really it boils down to what those flavorings are made of.
Take a wiff and a taste, let us know how you feel about it.
