I would hope the 7 does have a warmer screen and was glad to see reviewers mentioning this, thing is if it's closer to 6500K this is actually a good thing, the 6s screens were actually way too cold which was easily noticeable if you ever had to switch from a calibrated monitor or TV to the 6s as it was really blue, it might just be you are used to a inaccurate screen and maybe you even prefer that but the 6s screen wasn't accurate, sadly companies have been using colder and colder screens recently and people seem to think warmer screens are always bad and colder ones are good. usually out of the factory TV's, monitors and phones are way too cold and when most people I know see one calibrated correctly they think its too warm because they aren't used to it.
also screens of course will vary phone to phone and of course people will get ones that are too warm, my point though is lots of people seem to be mentioning warmer screens with the 7 which might not be a bad thing if they are actually more accurate on average if that makes sense
