「どうあろうと」と「どうあっても」 の違いは何ですか


In this example sentence from the manga Death Note,

"推理の過程が **どうあろうと** この女の握っている事は真実"

When I looked for the meaning on weblio it suggested どうあっても as meaning the
same thing? My Rikaikun doesn't come with an answer for どうあろうと but it knows
どうあっても, are they roughly the same meaning?

Thank you for your help! ありがとうございます！




どうあろうと No matter how (推理の過程) would be

どうあっても No matter how (推理の過程) is

I think the semantic difference is small in the context.

> この女の握っている事は真実

This part baffles me as to the meaning of the whole sentence. この女 did the
detective work?
