Cylinder wall problems ( never seen anything like it)

The wall pattern and discoloration in pix 1 and 2 looks like 'gas washing' on the cylinder walls; the oil is being washed off by something, perhaps excess gas or alcohol or chemicals; the wall is heating due to something. This type of discoloration will happen due localized heating of the wall due to the oil being washed off. How were the rings?

What is in your fuel? I can understand the E85 perhaps washing off oil.

Can't say anything on the 'dents' in the wall....that is a new one? Or perhaps a really bad case of the oil washed off.
