(Edited) The frog was on the low-res developer device.
The much larger “8k” version introduced half way through https://www.youtube.com/watch?v=-EA2FQXs4dw has some good tech detail, with the raw pixel mapping shown at 6:30. Calcs seem about right since raw pixel count was stated as 43 million, although it was implied elsewhere they split RGB sub pixels too (which sounds wrong I admit), so maybe 43 million divided by 15? Our eyes are more sensitive to luminance than colour, so maybe they did something there (however, not that I could see from the raw pixel mapping at 6:30).
If they're counting subpixels as separate whole pixels and omitting the fact that the "effective" resolution is much lower because of the 3d layering just so they can say "8k" in their marketing material that's suuuper dishonest.
