When using custom compiled kernel (4.19.81-v7+) or the latest beta kernel (via rpi-update), frame buffer has 16-bit depth only. Setting framebuffer_depth=32 makes no difference. Also X server displays 16-bit colors only. This does not happen when using the kernel 4.19.75-v7+.
I would expect 32-bit frame buffer by default or accepting framebuffer_depth=32 in /boot/config.txt.
