Check if you can enable all the 4K and 1080p resolutions in Kodi's System-Display-Whitelist then videos will switch to 4K resolution when they start playing.
If you only have one option here then your tv manufacturer, Phillips didn't implement the Android Mode Setting API that was released since Android Nougat and you have to contact them for a firmware update to fix the issues. AndroidTV on actual tv's have broken firmware most of the time, that's why people use external Android media players and only buy tv's for picture quality, not for their OS features.
Sorry for a very late update, some personal matters came in the way.
Anyway I think I can verify it works?
Even though Settings > System > Display lists "Resolution" locked at "1920x1080p" when I try and play a movie that is 2160p I can see it reports as "3840x2160" under "Video Steam" when pressing the letter "O" during playback and it also toggles HDR.
The question as a previous user also asked is:
Is that the actual resolution on my TV (i.e. my TV is outputting 4K) or is the videostream 4K but the TV outputs 1080p (and therefore downscale it) as stated in Settings > System > Display?
Also I tried checking the Android API to find what you mentioned ("Android Mode Setting") but couldn't find it, can you please elaborate if I am going to pester Philips about it?

"To have the availability to stream the apps in 4K the have to compatible for it. If the apps is not available to provide 4K, it will not be possible to have that resolution.
Yes the TV is and Android operating system based, but it has limited functionality compared to the original operating system from Android. "
Great work and thanks for sharing, I'll try and contact Philips after I know what to contact them about and see what results I get
