Dolby Vision just doesn't hit peak brightness like HDR10 does. Should be better than HDR10 no?

It DOES look better than it used to, but just can’t compete with HDR10. Shows and movies on this LG G3 look stellar in Dolby Vision yet these games just fall short. It’s like there’s some weird brightness limiter. My G3 can hit 1500 nits and I see this happen quite often in HDR10 on this console. Dolby Vision… not even close. Looks like it’s hitting MAYBE 1000 nits.

This isn’t a Forza specific problem, but I just don’t know how to get this to the xbox team. Y’all tout Dolby tech really hard yet it just doesn’t deliver. I expect much better looking HDR with DV. This just isn’t cutting it.
