Parameter for background:

-b - set background colour 16 bit RGBA e.g. 0x000F is opaque black

In the description for pngview, we can see that background is 16-bit color with RGBA format. But on raspberry pi 3 and 4 I can see different behavior with this color format. Pi 3 use an RGBA format(works as expected) and Raspberry pi 4 use a BGRA format.

It has some dependency on a specific library for GPU?

Fix different splash screen colors on rpi 3 and 4.

For some reasons pngview application use different image format
for background on rpi 4(on rpi 3 all works as expected). Therefore
provide workaround which detect board version and change background
parameter for each board.
