output from edid-decode from hacked EDID file

I have a tv that does not handle YCbCr properly but advertises it in his ED=
ID.
So I have to force Full RGB over HDMI because it seems that my RX 570 uses
YCbCr by default (maybe because of the HDMI connection?).
There is no switch to force Full RGB so I downloaded the EDID with get-edid
using i2c and hacked it to disable the advertisement of YcbCr. I copied it =
to
the initrd and force loaded it via drm.edid_firmware=3Dedid/PhilipsFTV.bin.
It works:
[    0.000000] Kernel command line: BOOT_IMAGE=3D/boot/vmlinuz-5.0.0-trunk-=
amd64
root=3DUUID=3D1c91ef55-0cf6-4694-bd2a-29aeb6492b3b ro
drm.edid_firmware=3Dedid/PhilipsFTV.bin
[    0.849967] platform HDMI-A-1: firmware: direct-loading firmware
edid/PhilipsFTV.bin
[    0.850055] [drm] Got external EDID base block and 1 extension from
"edid/PhilipsFTV.bin" for connector "HDMI-A-1"

But the problems with my tv persist. So I think that the forced EDID is ign=
ored
by AMDGPU.
