You have access to the official OST of Doom Eternal (which is claimed to have the brickwalling), as well as access to the in-game versions of those tracks (which you can rip out of the game or find the already-ripped ones on youtube easily). I can certainly confirm by playing the game and listening to the ripped files myself that there was no brickwalling in the in-game tracks. However, it becomes very obvious in the official OST.

Interesting. My initial comment was discussion of the article only. This additional information, which is not mentioned in the article, makes it seem that the brickwall mastering was not done by Mick Gordon.
