Not positive, but I think for white point you're talking about your subjective preference for a warmer or cooler display. As an example, the S8 and S9 devices have a white point that is calibrated too low, at 6150-6250K. Smartphones, like monitors used for photograph editing, are calibrated to D65, which is 6500K. This is slightly more blue than D63, which is used for cinema content in a dark theater.
Now, I don't know which display settings you use on LG phones, but you are almost definitely not looking at Samsung phones in "basic" mode, which is the sRGB color accurate mode that they have. Out of the box, they are set to a much heavier saturated mode that skews colors a lot. The LG V20 as an example, has a white point of about 9250K, which is WAY off of the perfect setting of 6500K. It also has an extremely large Delta-E on the sRGB calibration. The LG V30 brought their white point down to about, 7825K, which cut their error percentage in half. That's an LED display, right? It's only 20% deviated from perfect, while the LG V20's LCD was 42% deviated. If you're looking at the LG V20 and thinking, "this looks good" - then that just means you have a preference for inaccurate colors.
In general, numbers higher than 6500 are going to appear more blue and numbers lower are going to appear more red - but, they're also relative to each other - the Pixel 2 XL has a white point of about 6800, which is less than 5% deviation and it will look more red than the V30 and V20, but more blue than the Note 8, which has a white point of about 6475, which is less than .5% deviation and is one of the most perfect displays out on this metric. So if you are used to the overly cool (values significantly higher than 6500K) display, than the warmer displays, even if they're still cooler than perfect, are going to look off from that subjective standpoint.
The most important thing, is that even though these displays look "more red" (warmer) than what you are used to, that does not mean they are inaccurate - quite the contrary, every device I've just named is far more acculturate on the display temperature metric than every LG flagship made in recent years. Here's a chart to display the most recent Apple, Samsung and Google devices and how they rate on color temperature:

As you can see, compared to the industry standard - which is the same standard used for PC monitors used by professional photographers - the recent LG flagships are wildly inaccurate on color temperature. I threw in the Nexus 5X as well though, as it is produced by LG but calibrated Google's display preferences, not LG's. As you can see, the Nexus 5X was night and day better than anything LG does on its own - nearly 4 times more accurate on this metric. This supports the conclusion that this is an intentional decision being made by LG and not related to the type of display being used. The V30 and the Pixel 2 XL share display tech and are both made by LG - and the Pixel 2 XL is nearly 4 times more accurate on white point than the V30. This also supports the conclusion that LG is intentionally making their displays significantly cooler than the rest of the industry.
So to reiterate, LG is intentionally making their displays with an extremely cool color temperature that can have an immense impact on your perceptions when looking at (technically) better displays because almost all displays are going to look extremely warm compared to the wildly inaccurate temperatures of LG's display settings. This is the main reason that we use tools to measure these things, rather than eyeballing it.
