Turning down the backlight to six or seven reduces the problem but certainly does not eliminate it. But as I said earlier, since I have experienced a couple of Sony televisions in my quest to find the "perfect" television (it doesn't exist) I have come to the conclusion that Sony has a better picture quality according to my personal experience and opinion.
I always set the Sony to movie mode and warm2 settings so it's not a case of me wanting or preferring an ultra-vivid cold color temperature. I'm actually happy that the Sony doesn't have an in-depth color management system because quite frankly it does not need it. Sony has the color right out-of-the-box and there is little to no need to adjust or manage the color outside of adjusting the "color" setting a couple of degrees. Sony televisions do have a white balance adjustment that can be used to correct the orange tinge in the Reds but after about 10 min. of watching the television you become quickly adjusted to the slight error and you really don't notice it anymore.
I have played around with the Samsung in relation to settings and color management and frankly have just given up. I have tried a number of different setting suggestions in these threads including yours and they all just seem to turn out the same. With the Samsung the result for me is generally an overall yellow tinge to every color but blue. Skin tones seem yellow, greens seem yellow, etc. Don't get me wrong, the Samsung is a beautiful TV and does a wonderful job but I just think that Sony does a better job in regards to picture quality and color accuracy at least for my tastes. :-) :-)
I'm going to be trying the Sony KDL65W850A as it is being delivered hopefully by the end of this week. I've heard some great things about it and I'm hoping that there won't be any major issues with screen uniformity on this particular unit. I've tried the KDL70W840B which I found to be a spectacular television with only two flaws. The first was the radial banding (which wasn't very severe on my set) and the second was the Motion Flow xr240 wasn't quite enough to keep up with fast movements (this is something the Samsung does very well). I also tried the KDL65W950B which I found to be extremely good in every way except for the black levels due to the IPS panel. I would have kept it if it weren't for that. In fact, if the W850A doesn't work out, I'm just going to go back to that television and live with the poor black levels as it excels in every other way.
I do hear you. We are certainly all pursuing the best picture quality we can get from our TV's, and everyone tries to get the best performance and bang for the buck. The H7150 is one of the better TV's of 2014, and especially in larger size (like the 75" I went for) it is a great value. A TV that would top it's performance in that size would be practically double in price and start at $6K+, forcing 4K resolution (which I find unnecessary at this point), etc.
Now in terms of color accuracy and overall performance, I find it hard to believe you would be better served with a similarly priced Sony TV as of today, especially a model with not the greatest black levels or contrast ratio. The yellowish tint you mention on your Samsung is certainly correctable with proper calibration, although surprising that it would be as prominent as you seem to experience even without calibration. Maybe you really have a somewhat "off" or defective panel in some way, but likely you just need a properly calibrated grayscale (copying other settings does not guarantee such correction at all btw. and is not a sign of something being wrong with your TV or necessarily needing replacement). Interestingly, the orange-pushed red on Sony is something you can get used to but not the likely correctable yellowish tint of your Samsung set... Be that as it may, I would certainly think twice about giving up on calibrating out the yellowish tint and sacrificing in contrast and black level (apart from motion handling and achievable color accuracy), which are probably THE most important aspects of good picture quality...
I say this as something I would suggest to anyone and with best intentions, not as a fan of Samsung or having anything against Sony at all - (if it was up to me, we would actually still have Panasonic plasmas on the market). Sony does offer some good TV's, especially in the high price bracket. Their color accuracy is relatively good out of the box, I agree, although not as "perfect" as one can achieve on a Samsung, which is btw. particularly known for fantastic color accuracy. Also (as a side note), the grayscale adjustments on a Sony are unlikely to have much effect on a tint of red color specifically. So if you are looking for color accuracy, going away from Samsung (and to a TV that doesn't even offer color tuning) is likely not the right move (I would view the yellowish tint as an anomaly, which if not correctable with some grayscale tweaks suggests a replacement under warranty as appropriate...).
In the end, I hope you make the right choice that will make you enjoy your TV, whichever model or brand it may end up being. My only advice is not to perceive your TV as bad or defective because some shared settings didn't translate on your panel and didn't correct some yellowish tint - that only mans your TV needs it's own proper settings. If truly defective, I'd just replace it under warranty rather than go for less contrast, or worse black levels, etc. Anyway, certainly good luck in your final decision
