So, I searched, and I find a few older reports on a similar issue (dating from 2020ish) but when I enable HDR in the Vulkan settings, Doom just ends up looking extremely washed out. I'm playing on an HDR-capable display, and don't have that issue with other games (with the exception of one, Ghost Recon: Breakpoint, which acts extremely similarly, washing everything out when HDR is enabled). I'm on Windows 11.
I took screenshots, and the screenshots preserve accurately what it looks like.
