I was readings rtings site and this thing caught my eyes.This looks like the top tier expensive may have a 10bit 1.07b colors but is not officialy advertised ?
The gradient handling is exceptional. There's minimal banding throughout and you shouldn't notice any banding with real content. It's advertised to have an 8-bit panel, but we can achieve 10-bit in the EDID of the monitor, so it may be 8-bit with FRC, but we don't know for sure. The max refresh rate with a 10-bit source over a DisplayPort connection is 300Hz, and 144Hz over an HDMI connection.
This one the same 10bit mode at gradient:
The 360Hz is only achievable over a DisplayPort connection, and it caps out at 300Hz with 10-bit HDR. Over HDMI, the maximum refresh rate is 240Hz and 120Hz with 10-bit HDR. G-SYNC works over HDMI and DisplayPort.
The 10bit mode limits refresh rates.So they can't advertise the monitors as 10bit because the refresh rates are changed.
So after all seems there are 10bit 1080p gaming monitors. This is intersting.The DCI-p3 and Adobe RGB are around 76% coverage...
