If it’s washed out, it’s either that there’s a mismatch in pixel format, like u/scutiger was saying or you might be used to oversaturated sRGB, as by default displays are set to stretch the input to their entire range (which if it’s HDR should be close to DCI-P3). sRGB colors shouldn’t look different when displayed in HDR, unless something is misconfigured.
I’m considering trying to host my own mail (receive and internal send only, at least at first), as I have a friend who’s hosting all the useful services and mail’s the only one left.
Also experimenting with (rootless) podman, I’m finding the permission mapping a bit confusing tbh.
