Okay I've done some research on it, its 2407-WFPb-HC and is 92% NTSC.
Turns out though that normal programs / drivers don't support that so I'm not sure if I've ever even viewed it in "high color" mode I just plugged it in and used it so its probably running in normal mode all these years.
According to my research, its really complicated.
First there are "TN" panels, which are 6bit per channel of RGB (262,000 colors not 16,000,000 colors that 24bit/32bit color is truly capable of). Most gaming monitors use "TN" for fast response, most budget monitors use "TN" for low price. It cannot show good colors, and you should try to not use these monitors for graphics as they are all washed out and have really bad grey levels.
Then there are PVA/MVA/IPS/etc panels with normal 8bit per channel of RGB (full 16,000,000 colors just like the old CRTs), these are the so called 100% sRGB monitors, and that's all you need and all that most software can use.
THEN you have "special" 92% NTSC monitors, these can display more than is capable with 24bit/32bit color 8bits per channel RGB. Which means in order to make this work, your graphics card drivers, windows settings, and program you are using all have to do some funky custom color format shit to make it work. And even then you won't see a difference except in gradients you paint in photoshop, and if you have any 10bit video files or 16bit channel PNG files.
Heres a video that explains this bullshit
