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.

DVB was broken in 6.1.52 and fixed in 6.1.53. LE 11.0.4 use kernel 6.1.68. So this must be something else.
but it seemingly affects these TV tuners in TVHeadend
This was fixed by https://github.com/torvalds/linux…4c05c89f46e41d1
LE can be built with Wayland. It would miss some crucial features like refresh rate switching. Also Kodi does not support HDR passthrough on Wayland.
It's better we think how (and when) we can drop it too.
It was dropped since LE 11 and now used only in Generic-legacy.
TL;DR version that "max bpc" property is 0 at boot and your script bumps it to 10?
It is 12 at boot. 12-bit seem to cause an issue with audio passthrough at 4K/23.976 mode.
You better open a Kodi github issue with all the required info/logs and a sample of a .ts recording.
