Well....it's packaged up for return.
Installed StillColor and tweaked and messed with the laptop...and no matter WHAT I did, within about 10 minues of using it, I'd get a 'burning' feeling in my eyes, a pretty good headache, and nausea. Switched back to my MBP M2 Pro, and within 5 minutes or so the feeling would go away.
My wife was wondering if I was making things up, so I asked her if she noticed it. She started using my MBP - no issues. Soon as she started using the MBA....within a few minutes she complained that HER eyes hurt and it gave her a headache. She actually apologized for giving me junk over the last few years.
Not sure why it bothers some and not others. I love the MBA form factor but can't deal w/the screen, so back it goes.
