Maybe add that (IMO) you should mostly ignore the maximum value. It's usually from hot/warm pixels anyhow (unless you're really overexposed).

ASIStudio has it's own default settings, as Max says, and tweaks the white balance. That is a definite no-go for proper astro processing as the ZWO driver/library changes the raw values in the FITS file if your WB isn't 50/50. So (in EKOS) verify you're at 50/50, then look at the mean/median in the channels. Those of your example do look fine, this is normal.
Maybe also switch the saturation display on (red dot button) and verify that the maxima are just single pixels and not extended areas.
