Mmm, I don't know where my math came from.
8dp gets converted to 15 pixels.
The bars (and spaces) in the shots are 2 pixels each.
The 45° does show 15 pixels (4 bars + 3 spaces + 1 lone pixel at the bottom).
The straight-on shows 10 pixels (3 bars + 2 spaces).
Losage is 5 pixels.
OTOH, if you read with the devices tilted a bit away from you you lose another few pixels.
That justifies the 4dp for normal devices, 8 dp for Poke3
