Movies Mastered at 4000 nit or more is getting less these days

[Blackman]

I have a Oppo UHD 203 and also a Panasonic UB 9000 that spills the info on all UHD Movies (DML MaxCLL MAXFALL) and I find now in the year 2023 to 2025 movies are getting mastered more at 1000 Nit Compared to Movies mastered at 4000 nit.
I remember the days when at least 35% of Movies was Master at 4000 nit and yet today you lucky to get 10% of them mastered at 4000 nit and since I have a Sony 85 Z9G that give close to 4000 Nit I feel that I getting Cheated on this or am I look at this the wrong way.
I also out the Back Living room I have a Sony 85 Z8H than give a peak Brightness of 2400 Nit @ 10% and I think the Z8H has better blacks possible better contrast because as you know why have a cannon that burn your eyes and at the same time it poor in blacks.
What do you guys think? Is it better to have a UHD TV that can muster on or less 2000 Nit of peak brightness for a LCD or Mini Led LCD but at the same time give you the best Black level that you can get for this technology.
Thanks
