You are trying to play a Dolby Vision video.
If you can compile your own LE image you can try to build it with this patch removed. This will enable async rendering and should improve GUI performance quite a bit.
Did you disable "Disable screensaver when playing audio" setting?
Is this a bug, or a limitation of driver/software support as noted in the docs?
I don't have an RPi but I think this RPI-specific patch does the bit depth detection and sets the HDMI mode accordingly. No idea why it does not work for AV1 though.
When I changed channel it flickers
This was fixed in Kodi 22 "P", so wait for LE13.
signal HLG not work in TV LG
Try this build.
IMO it's worth trying the new Intel Xe driver.
CONFIG_DRM_XE=m
i915.force_probe=!xxxx xe.force_probe=xxxx (disable i915 and enable Xe driver, xxxx=Intel PCI graphics ID)
I'm running this on TGL and kernel 6.9. No idea if it fixes anything, I don't use audio passthrough.

It's probably related to AAC audio. See here.
flickering deinterlacing
That's BOB deinterlacing. RPi4 can only do BOB when using a hardware decoding. For high quality deinterlacing (BWDIF) switch to software decoding.
Back in pre-LE10 days there was a MMAL (GPU-assisted?) high quality deinterlacing method but I doubt that it would ever be re-implemented.
Maybe some setting on that TV is forcing an HDR mode?
I wonder if YUV mode can be forced by editing EDID?
RGB support is mandatory, it's not possible to to disable it in EDID. Intel driver defaults to RGB and they don't provide a way to switch to YCbCr from the userspace.
I looked and I can't find a/drivers/gpu/drm/i915/display/intel_hdmi.c anywhere
need to modify the code and recompile
^ This. There is no other way other than hacking the kernel.
That EDID does not have HDMI-Forum VSDB (vendor-specific data block).
Check your TV's HDMI related settings. I am not familiar with Panasonic TVs but on Samsung you have to enable "Input Signal Plus" to enable HDMI 2.0 EDID. There must be something similar to that on Panasonic.
Upd.: looks like on Panasonic it is called HDMI "Mode 2".
m88rs6060 was added to CE 5.4/5.15 kernel to support TBS 5930. A working m88rs6060 driver is not enough to make the internal tuner of that mecool box work.
