Desktop mode snaps to 8bit to conform with Windows as it should. 10bit also snaps for all other resolutions such as 23/24/25 Hz when applicable. Note this is FSE with 59.940fps @60Hz. Never uploaded a file here so bear with me if it doesn't upload.

HDMI 2.0 doesn't support 4K60p 4:4:4 at 10bits, it's above the 18Gb/s limitation, so it can't work. You have to output 8bits at 4K60p.
Have you selected 8bits in 4K60p when playing a first 4K60p video with a standard resolution? I think that's how the driver knows what to switch to in the first place, but I could be wrong.
Attachments here take ages to be approved, so better use other means (simplest is a link to an unlisted Youtube/Vimeo video). There is no need for a video, I believe you
Instead, can you list the information I suggested to list if the steps I outlined don't work for you?
