DT 3 vs 4 inconsistency

Upgraded DT to version 4. What I don’t understand - why are there differences in tones and colors between DT versions with exactly the same edits?
An example below - first image edited in 3.8.1, then pasted on a duplicate the same history stack after upgrade in DT4 (with filmic v5 of course, same colour profile etc., nothing is different in the settings of the modules).
Is there a setting somewhere in DT which I missed? How to get the same results like in DT3?

Can you provide the two sidecars?
Did you use append or overwrite mode? Also, copy and paste don’t transfer all modules (for some, one has to use selective copy/paste).

Probably DT’s new color science in colorbalance rgb. You can go back in the module options

I found the reason. I discovered that an automatic low-pass filter was turned on.
I didn’t think the program would automatically apply it over and above the history stack.
Sorry, I wrongly assumed that the problem was caused by the version difference.

Thanks (és köszönöm).
