( By the way, it's easier to diagnose in photos if the chainring is clean. )

Here's a crop, rotated, from your photo:
The two teeth on the right are machined to that truncated shape at the factory. It's designed to help shifting onto the big ring.

The shiny wear on the face of the teeth is normal, and doesn't affect performance.

The back sides of chainring teeth often look "rounded off" or "worn down", but the chain doesn't press against those sides. It's just shaping to help when shifting. The ring turns clockwise, so the chain rollers press against the right side of the teeth.

The teeth at the pink lines might be a little worn. But like the other comments, it's probably still okay.
