Yes, you are seeing curved straie. They are hard to distinguish, but are not ruler straight. The bottom picture shows them best.
The gas bubbles are as you expected. Most crystal inclusions have straight sides and often pointed terminations, although partial melting can confuse this. These are clearly bubbles.
Any time you find a loupe clean sapphire of significant size, it is most likely a synthetic and deserves careful examination!
