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.

why can I not playback UHD when watching TV via HTS client on Intel systems?
I've seen this with HDR (HLG) 4K channel. Regular SDR 4K channels work fine for me.

wondering if we could disable this option at the kodi gui as it just creates problems ?
IMO this should be done upstream in Kodi, e.g. if platform supports VAAPI then DRM PRIME option should not be present in GUI.

What are the chances that the 11gen intel chips get fixed?
As you can see on this block diagram, NUC11PAxxx does not have a native HDMI port. It is using a DP->HDMI protocol converter (PCON) chip. It is more than likely the source of your audio passthrough issues. So this is not a gen11 issue but an issue specific to that NUC model. There is nothing to fix from LE/Kodi side.

No. DRM PRIME was never properly implemented for x86.
