The difference is significant. In the second case, how was it processed — with channel separation? At least briefly.

Hello, I didn't separate the channels here, although I should have. Honestly, I can't quite remember the process itself. I think I was learning how to stretch properly in Siril at the time, and this is mostly the result of correct stretching through GHS.
