I’m also on Leia and I also have problems with 4k HDR and 10-bit. (Kernel 121)
The biggest problem is with 4k HDR 60 fps movies (mainly tv test samples from LG, Philips and Sony)
When I whitelist 3840x2160p 59,94Hz there are no picture at all when I play them.
When I disable that resolution - 4k HDR 10- bit movies plays but only in 1080p and 24-bits.
In SSH (echo now | sudo tee /sys/class/amhdmitx/amhdmitx0/attr) I see Colour Depth - 10 -bit and Coluourspace - YUV422 but there is certainly no 10 bit colour on my screen (to test I am using LG Cinematic Jazz 4k Demo.ts).
On Krypton build everything was fine on every file I tested.
When I show info about source on my receiver I see 24-bit YCbCr422 and 1080p and 59Hz
When I play 23,978 movies in 4k my receiver shows 4k 24 Hz but also in 24 bit YCbCr422
There is something wrong…I know it is a test build…I only want to say there are some problems to resolve.
There is no possibility to return to Krypton without installing it from beginning?
Leia is very fast…everything works great except 4k HDR 60fps and 10 bit
I don’t know what to do…wait for upgrade or instal Krypton…
PS: There is one bug…every time I restert Vero I need to recalibrate my screen
