I have a slight pink hue as well (60") (I almost returned it because I was so upset but then I slept on it and actually thought about what I got for the price) and can notice the display if i'm closer then where my seats are currently located. I figure at the price point, I can't beat it. I calibrated it with some settings I found on here, then used my Disney WOW to really dial it in.
The pink is not noticeable at all during normal playback (maybe I got a good one)? The display is fine as long as your far enough away. I just added some bias lighting to it yesterday and I love it. The picture is excellent. Play some HQ Youtube videos (usually 4k but only stream 1080P), and you'll be blown away.
I don't plan on upgrading until a 4k projector can come in around $3,000.
