Ultimately, it's your TV, so don't feel like you need to set it in a way that doesn't look good to you.
There's also a limit to what you can simply copy settings for. Panels tend not to be exactly the same, so while values from other forums may be a place to start, you'll want to tune some parts of it yourself. As mentioned/implied, you may have some discs that include some basic reference material on them. You could also buy a dedicated disc that has them (though many aren't cheap) or simply grab patterns
from online.
That said, there's only so much you can realistically accomplish by sight. Professional calibration utilizes a color meter and service tools to objectively adjust the hardware...but costs enough that it's not likely worth it unless you have a pretty pricey TV to start with.

Some people say contrast should be 100 while others says that will give you the “showroom” effect. brightness and backlight are another confusing ones. Color temperature is another thing, my tv has a “movie” setting but it so obviously has a yellow/brown tint called “warm”. Is this how it should look like?
Sharpness is largely a holdover from analog TV. So, it may have some use on scaled content or something...but for digital content at native resolution it'll probably be more of a negative than an improvement.
Brightness/Contrast/Backlight really can come down to the performance of your panel combined with the viewing environment. TVs often have settings for Dynamic Contrast/Black Level, which you probably want to lower if tweaking these.
Backlight is the simplest setting here. This is your literal "brightness" control, and the biggest consideration is essentially what your TV is competing with. A TV in a bright room, particularly one with a lot of natural light, needs to be putting out a lot of light itself or it'll look dim and lacking in detail. On the flip side, you don't want to be squinting just to look at a TV that's the only source of light in the room, so it can (and should be) set lower. This is also where to consider
bias lighting, if you have a dark room.
Brightness and Contrast themselves are, in turn, a little different on modern panels. They're effectively black level and white level. There's a nice visual guide to them
here, but this comes down a fair bit to what your panel is actually capable of. Older or lower end TVs may have issues displaying a lot of detail in dark areas of a picture.
The above settings, in particular, tend to be the ones that are set differently in stores as opposed to in home. Retail stores tend to be big, bright places and a TV needs to be set bright and bold to stand out. A home environment tends to be darker, so you can run less extreme settings that allow for more subtle detail to be shown.
Color temperature
shouldn't come across as an extreme in either direction. "Warm" settings skew more toward red, "Cool" towards blue (which also looks bright, and is in turn what most devices err on the side of). It should look neutral, and that's something you may be able to tweak manually.
