Great, I'm closing the issue then.

When using TeX-view to open the current configured pdf with synctex
forward search, the evince pdf viewer does not inherit or load
environment variables from e.g., ~/.zshenv.

Other viewers like zathura or okular work perfectly fine.

When I do cat /proc/`pidof okular`/environ, I get the full environment
with variables from my ~/.zshenv, but when I do
cat /proc/`pidof evince`/environ I get a plain version with no custom
variables. When I start evince from command line everything works fine.

I suspect, that this is some issue about how evince is started via dbus
for synctex support.

Here is the output of cat /proc/`pidof evince`/environ when started from
emacs:
SHELL=/bin/zshDBUS_STARTER_ADDRESS=unix:path=/run/user/1000/bus,guid=bfDISPLAY=:0XDG_RUNTIME_DIR=/run/user/1000LC_MONETARY=de_DE.UTF-8LC_NUMERIC=de_DE.UTF-8PATH=/usr/local/bin:/usr/binMAIL=/var/spool/mail/fabianSYSTEMD_EXEC_PID=2137DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus,guid=bfXAUTHORITY=/home/fabian/.XauthorityUSER=fabianDBUS_STARTER_BUS_TYPE=sessionMANAGERPID=2051LANG=en_US.UTF-8LC_COLLATE=CHOME=/home/fabianLOGNAME=fabian

I use the following elisp code to set the viewer to evince (doom emacs):
(after! tex
        (setq TeX-view-program-selection '((output-pdf "Evince") (output-pdf "Zathura") (output-pdf "Okular") (output-html "xdg-open"))))
