Hello sentinelHub-Team,
thank you for your work! 
I have a small question for the result of atmospheric correction.
The result of L1A is in natural color (B4,3,2) brighter than L1C. That is okay for me.
The result of L1A is in geology (B12,4,2) darker than L1C. Why? Is there only a histogram strech left?
Example:
Greets
I am not an expert in atmospheric correction, but as two of the bands in geology are the same as in true color (4,2), it is somehow expected that result will be similar int erms of the darknes.
That being said, the “darkness” is not really relevant if you ask me - this is something you can easily fine-tune to your liking by using custom script option as described here:
