You are right! I just did a check, and the display is a Samsung G9N. The bottom is not reddish at all – it could be just the photo, which was taken under less than ideal lighting.
All be told, I’m actually pretty pleased with this display on the whole after comparing it to a few other displays the past few days. It’s not perfect, but then again, I believe no display is 100% perfect. There will always be some minor flaws here and there if one really looks out for them. Many of the displays seem to have strong blue shift from my experience, especially the 512GB units (looked at three of them). (Mine is a 256GB, for what it’s worth.)
