Apple

So I have a 49um7300pua LG tv and up until yesterday, I’ve always had the picture setting in cinema mode. I came across the optimal settings for ATV and followed the RTINGS.com settings guide for my tv. However now I feel it has a yellowish/greenish tint to it. I tried doing the color balance calibration and saw minimal change. I figured it has something to do with the white balance but I didn’t wanna mess around with those settings since they’re a bit confusing.

I guess my question is, does the Apple TV color balance calibration correct the white balance to? Maybe my eyes aren’t used to this color change and it’s actually correct Or should I mess around with the white balance on my tv?
