After testing, I think I will leave it as it is.
Emissive=30 & emissive=50 is unrealistic and Arcade to me (furthermore that flags are not that pretty)
Maximum emissive you can put to keep some realism (if we can talk of realism) is =10…
Using SD3 it takes 10mn to change both files flags emissive, so if you feel (or need) to do it you can adjust it to your liking … but as everyone’s liking is different … and everyone’s monitors settings are different … best is to keep what we have
