Hi, I recently bought a SpyderX Pro to calibrate my P2715Q used exclusively for photo editing. There's a "Display Technology" Setting during pre-calibration that makes you pick a backlight option between, "Wide LED", "Standard LED", "General" (CCFL) or "GB LED".  My initial research seems to suggest this monitor would fall under the Standard LED category, with a description of:

"Standard LED -- Select this if your monitor has a standard gamut (color space) LED backlight. This is the most common modern backlight technology. Common monitors that fall under this category include Apple displays from 2009 to mid-2015, Dell U2412M, most notebooks and ultra-thin display."

After selecting this option and calibrating for 2.2 gamut, 6500k White Point, and 180 Brightness, I can't help but think my monitor looks a bit green after calibration. Is this the correct LED setting? Is Spyder still junk even after the X series (I've seen some people say Spyder is not good)? If I factory reset, do I get my original Factory Color Calibration that supposed to be very accurate? Do I need to buy a different calibrator if I want accurate colors still (my understanding is your calibration degrades over time and it's been several months since I bought the monitor)?

Thanks in advance!
