Does JB4 clear catless downpipe code ?

Some people say Jb4 clears the catless down pipe code and some people say it doesn’t, can anyone give me a clear explanation on this ?
I have a b58 340i

Depending on which JB4 model you have you can choose to "hide" codes that you are aware of such as the code caused by a catless downpipe

If you update the firmware, it will not allow auto-delete (aka "suppress") the catless downpipe CEL. I haven't checked to see if you can manually clear it, but even if you can, it will return in 50ish miles. I've just left my CEL on for a year.

You can switch to boot mod3 which has the auto-delete feature or get an o2 sensor spacer:
