I will try to write about this problem to nvidia. Thank you. Do yuo know where can I ask about?
I have two nvidia shiels and same problem. I buyed thes used. I hope there will be no problem with replacement.

 If they are out of warranty period then I guess purchasing a new remote is your best bet.  Mine failed 4 weeks after I purchased my Shield TV, new, from Amazon.

Colour space switching on my LG OLED (2017) through my Onkyo AV is working perfectly using the test update.

Here also perfect switching. With this feature the shield is King of the Hill again.

We still need global refresh rate switching...

Yep working perfect now on my Shield. Not bad for $6!

Which one did you go for Bluetooth or dongle?

Bluetooth.
Nvidia supports Bluetooth.
Dongle have the problem of sometimes having to point directly.

Colour space switching on my LG OLED (2017) through my Onkyo AV is working perfectly using the test update. 

Color space switching isn't working for me unfortunately. I also have an unexpected bit-depth change from f/w 7.2.1 to 7.2.2 (with 23.976 4K HDR videos now playing in 8-bit, vs. 10-bit before). All testing via Kodi 18 RC4. I have my Shield at recommended display settings. I'm using my Optoma UHD51A projector's info display on screen to verify. And, I've tested both via my AVR (Yamaha RX-A3050) and directly to PJ; same results. I also have a Zidoo X9S media player and a cheapo AMLogic S912 box w/LibreELEC installed, and switching works as expected on both.

So, with Shield, playing 4K HDR videos, I get 2020 HDR. With standard 1080p videos, I get 2020 SDR (not 709 as expected). When I play 4K 59.940fps HDR videos, my PJ indicates 4:2:0 10-bit (correct). But, when I play 4K 23.976fps HDR videos, my PJ indicates 4:2:2 8-bit (incorrect I think). I was getting 10-bit with all 4K HDR videos w/7.2.1.

For comparison, with my Zidoo X9S (set to 10-bit) and S912 LibreELEC boxes, I get 2020/709 switching and the same bit-depth results. With 23.976 4K HDR videos, 10-bit 4:4:4. And with 59.940 4K HDR, 10-bit 4:2:0. Both correct I believe. With Zidoo, if I set it to 'Auto' for deep color mode, for 23.976 4K HDR, I get 12-bit 4:4:4, and for 59.940 4K HDR, 12-bit 4:2:0. These also are correct I believe.

Just making sure but have you enabled Developer mode and then Colorimetry. Also I have mine set to YUV 422 12-bit Rec.2020.

[hdmkv]

Someone on nVidia's forum reminded me I needed to do that, so just did so. Forcing my Shield to YUV 422 12-bit Rec.2020, whether at 23.976, 59.94 or 60 makes no difference to my still getting 8-bit 4:2:2 for 23.976 4K HDR content.

Does your display give an HDR indication when it gets the signal?  I would imagine it wouldn't if it's only getting an 8-bit signal.  My LG OLED doesn't give much as far as specifics to what signal it's getting, but I can tell if it's 2020 or 709 and that's been working fine.

[hdmkv]

Yes, it does. I get HDR signal even with 8-bit, but when it's indicating it's getting 10- or 12-bit, PQ has more pop (or maybe it's placebo). Know @wesk05 has mentioned that several displays get the bit depth wrong (even when actually rendering 10-bit), so who knows. I'm thinking of investing in a HD Fury Vertex.

[olevelo]

Hmm, that's pretty weird.  HDR and 8-bit are mutually exclusive so something is going on in your chain somewhere.  I'm assuming it displayed all of the proper indications before the update?  You should be able to disable the colorometry setting to test out as well.

 It's entirely possible to flag an ST.2084 PQ EOTF (i.e. HDR10) in an 8-bit HDMI signal.  AMLogic S905X devices used to do this without being forced into 10-bit or 12-bit output modes when playing HDR10 content on some builds of LE.
