Very recently I bought my first new bike! I only did 750km on it so far. However the the chain rings are showing some level of wear, see picture. The teeth used to be all black, now you can see bits of silver on them. I just want to care for the bike with everything I can do. So let me know if this is because of misuse somehow.
Chainrings are special wear items in that they can be used even if severely visibly worn. It is very typical of used chainrings to show wear in the points that transmit forces, being a visibly different location than the points that don't transmit forces.
In some chainrings, it is possible to "rotate" the chainring on the crankset to even out the wear. However, your chainring seems to have these unfortunately new trendy non-even bolt patterns so "rotation" is impossible and you can't prolong the wear life of the chainring past what it experiences at the fixed orientation.
I remember seeing a picture of a chainring that was used either 300 000 miles or 300 000 km (don't remember which). It was by Jobst Brandt, the author of The Bicycle Wheel. That chainring was rotated multiple times in its wear life to even out wear. Unfortunately, I didn't store that chainring picture and it's gone from the 'net now. The 300 Kkm / Kmile chainring had practically no teeth left yet it still worked perfectly.
There's a long way to go until your chainring fails.
