I have an LG OLED and when using the U22 the HDR banner was displayed on the TV screen and changes to HDR view mode
But are you getting the actual "HDR 10+" banner & logo on your TV or just the typical HDR banner?
@jipo
Thanks for providing the link.
Im afraid HDR didnt kick in for me when playing on the T5 with Kodi 19
It did however when using my U22 also using Kodi 19 ( Coreelec)
Both Minix's are connected via an AVR to the same HDMI input port on the TV.
Minix claim HDR10+ support for the T5 so Im suprsied it didnt work

Just an FYI & some additional consideration for anyone in similar circumstances in the future...
..It probably hasn't worked consistently over HDMI in your case because your AVR doesn't support HDR 10+ passthrough, (to date there's still
very few AVR's that do in the grander scheme). Your AVR does obviously support standard HDR passthrough & it also supports Dolby Vision which is a similar concept to HDR 10+ but typically it's often the other way around with the playback devices themselves that may not yet have full support for DV too. It's still early days for both DV & HDR 10+, so we're essentially in that same "no man's land" that many consumers found themselves in when rushing to buy earlier generation 4K TV's a few years ago only to discover that their TV's (or AVR's if applicable) were immediately obsolete for any forwards compatibility for HDR, let alone beyond. (I've also had mixed results with HDR 10+ encoded files & the various different devices actually decoding the media through testing. (I.e the T5 or U22 with Android and/or CoreELEC.) Some HDR 10+ files I've tested simply default back down to standard HDR & otherwise display normally with my TV, some have constantly changing colouring issues that make the media unwatchable (presumably due to the nature of the dynamic metadata of HDR 10+ vs the static metadata of HDR 10 that my AVR isn't correctly passing through), or some files just won't playback or display anything at all. (On a side note, my TV definitely supports HDR 10+ via its own media player but over HDMI it's a bit of a grey area with the TV seemingly allowing it from certain HDMI devices but not others. So far there seems to be a pattern for premium devices allowing it over HDMI. I can't tell if apps like Netflix or Prime Video are successfully outputting in HDR vs HDR 10+ because the banners or info that used to be present have been removed in a recent firmware update so I can only be certain of the media being HDR & not specifically HDR 10+, make of that what you will.))
I have a feeling your TV will possibly have wider capabilities but your AVR is still obviously a limiting factor specifically when it comes to HDR 10+.
If you're also using notably older HDMI cables, they may also need due consideration for an update because of the significantly higher data rates involved that older cables may now struggle with. (
@jipo , you may also want to check all of your cabling as well if you hadn't already
.)
Otherwise, try playing the test file again or testing other HDR 10+ content via the TV's built in media player, (easily done from a USB stick or a NAS). Any change? (It'll be immediately apparent as the HDR 10+ banner/logo is quite different to the often plain standard HDR banner.)
I realise you're testing on behalf of someone else in this instance, but, if you want to know the particulars & capabilities of your specific hardware, then also try testing again with a direct connection from the device (T5/U22) to your LG TV as that "
may" allow full fat HDR 10+ to function, (so to speak). The audio should still come back down the ARC channel as well anyway, so you won't be watching a silent video
. Off the top of my head I can't remember if your TV & AVR both support e-ARC, but I have a feeling they both do so you can still get the best of both worlds in that regard, even if it's just to quickly test what capabilities your hardware may have.
HDR 10+ also has a completely different banner to HDR so it's immediately apparent to the viewer if they're viewing content in HDR 10+ vs standard HDR 10. Again, a quick test will help identify if your TV/system is handling everything correctly. Our AVR's obviously remain closely related & the stated specs are essentially the same in that regard so I'd avoid testing with the AVR directly in the chain as outlined above. (E-ARC "should" be OK.)
(I know it's a pain getting in behind all the various hardware to start swapping cables around especially just for a test etc. You may even be able to get the information specific to what your TV can/will support from looking up the discussions within the make/model owner's threads on another forum & save getting your hands dirty in this instance
