python - Python subprocess check_output return different result than running directly in terminal

Question

Running same command directly in terminal returns a different output than running via subprocess.check_output. Anyone know what is causing this?

running in terminal result a line Chip: Apple M1

but this line is not present if running via subprocess, instead this line shows up Processor Name: Unknown

strange?
