Yes it does allow me to check the box only when connected to my receiver, which is not altering the signal in anyway. For reference, I am using a Pioneer Elite SC-99 with the latest firmware. I does 4k/60 and HDR pass through.
I did test with the Xbox 1 S directly connected to HDMI 5 only, and it still allowed me to check the HDR box after selecting 4k from the drop down, then selecting 10-bit after. I think something is going on. The image quality is great and the TV is reading 4k res, but...I know technically it is impossible for it to display a 10-bit picture as it is 8-bit, and it has no HDR. But the Xbox 1 S is reading and showing that it is sending both. All I know is 4k Blu-ray looks really good but is not HDR.
Get this tidbit - when connected and using pass through HDMI switching from the receiver, I can even select 36-bit color depth (12-bit) and it will display. Again, the receiver is set to pass through and it has an up conversion feature that is off.
I have no expertise or idea why the tv is able to read these signals, or if the true signal indicated on the Xbox 1 S is actually outputting. I just know it is selected as I said and the tv has picture, and it looks nice...not 2016 P-Series HDR nice, but looks good and well formatted.
Note - PC also direct connected to HDMI 5 using the fore mentioned graphics card outputs also allows 10-bit RGB out at both 1080p/60 and 4/k 60.
Sorry I can't be more help with explanations as to why it is working, it just is.
