Spring Boot setting up Active profiles in an environment

I have a couple of Linux Environments into which my spring boot application is going to be deployed i.e QA & PROD.

If I set a System property such as thsese and pull them in the Spring Boot app to set the active environments,

ENVIRONMENT=QA in QA and
ENVIRONMENT=PROD in PROD

are there any potential limitations (technicnal, administration, continuous integration issues etc.)that I might face or is there a better approach to pick up the active environment?
