Has anyone noticed a difference in internal FX3 footage vs. ProRes (non-RAW) recorded externally?

Title says it all. I own an FX3 and have gone back and forth on if a Ninja to record ProRes is worth it. I already get great images but am open to getting a little extra “sauce” in the files with less compression and bypassing internal noise reduction that cannot be turned off when filming internally.

Thanks in advance!
