Miners: What kind of fee information do you see on our transactions?

[zorchy]

Hi there miners. I asked myself this question after some personal confusion (now cleared up) on fee estimations on Bitcoin transactions. Using a SegWit capable blockexplorer like Blockchair, I see that my transactions have three different fee calculations: per kB, per kWu and per kVB.

A non-SW explorer like Bitcoininfo only shows kWu, so previously thought that I had been spending fees lower than what they actually are, based on kVB.

But are all miners seeing SW txs like this?
