The black on all TVs has mainly to do with the panel used and nothing to do with the TV manufacturer. OLED shows a rich black, which is not possible with the traditional LED LCD panel, because with black there is always some residual light shimmering through. With colours in general, it is also a question of the panel. As a rule of thumb, you can say that more expensive devices have better panels and can therefore display more colours. You can therefore buy a Philips TV without any problems.
