Spring application packaged in jar is ignoring configured log level

Question

I have a Spring Boot (v2.7.0) application running in production for quite some time. There was a problem reported recently and for which I needed a bit more logs, and decided to change the logging configuration from INFO to DEBUG. After restarting the application the debug logs were still absent from the log file. Debuging this localy to noticed that the logging level in the application-{profile}.yml is only taken into consideration only when running trough InteliJ. I'm using lombok SLF4J annotation for logging and no logback.xml configuration override is presented.

application-dev.yml

logging:
  level:
    root: warn

./gradlew :app:bootRun --args='--spring.profiles.active=dev'

./gradlew :app:bootRun --args='--spring.profiles.active=dev'

> Task :app:bootRun

Tried running bootJar and starting with java -jar and passing logging overrides, tried to gradle bootRun and noticed that the configured level is still ignored and INFO is used.
