I hope this doesn't come off very rude or demanding, no intention for it to be; I was thinking of trying my best to not make it sound rude/demanding/intimidating, but I thought it would be best to say it in straight words. I really apologize if it does come off as what I hope it doesn't.
Just like the others, it's too bright; but this is a very subjective claim and depends on the monitor they're using. As for me, I have an HDR monitor so it's really bright, but not as bright when HDR mode is turned off; so, for the author, things may look amazing on your end since you remastered and tweaked it according to your own monitor.
You should listen to the reviews and suggestions but sending screenshots might be useless since when the consumer sends a picture of it being supposedly too bright, the screenshot might look perfectly fine on your monitor.
A good idea is getting a handful of reviewers, listen exactly to their inputs, tweak it based on that, send them a remastered version based on their comments on it, have them test it again, and repeat. Trial and error until the reviewer think it's perfect.
Once you have a couple of alternate remastered versions, you can release those. For example, Exquisite_PURE(HDR), Exquisite_PURE(NOHDR), etc etc.
This will definitely take some time, do it on your own pace, there's no rush. For the meantime, we can always go back to the 3.3 version, which is the most visually stunning out of all ppfilters imo.
Thank you again for developing this beautiful masterpiece!!
