As you know, the Nintendo Switch OLED launch trailer showed us a number of screenshots of Pokémon Brilliant Diamond and Shining Pearl. In them we could see a clear visual improvement over the trailer with which the game was announced.
Now, from Dexerto, they have offered us a frame by frame comparison of this graphical improvement. They have taken images from the first trailer and compared them with the scenes from the Nintendo Switch trailer (OLED model). Note that the footage from the first trailer is captured directly, while the second trailer footage is cropped from the video and therefore not shown in high definition and colour. However, the visual enhancement is clearly visible.
We leave them for you below:
You can also see them animated:
Here are all the scenes from the trailer of the OLED model:
