I beg to differ and I've owned an S23 Ultra. Colour luminance is good, not the best, nor is peak brightness and HDR10 compositing is definitely not best in class vs the 14PM, let alone the 15PM.Good to know the best phone screen in the industry is still the best. S23U undefeated.
Actually, the S22+ performed better with HDR10 performance according to XDA"s deep dive on the S23U display:

The Galaxy S23 Ultra has some improvements to the screen, but is it enough to make it one of the best phones with a Samsung Display?

Only the Google Pixel devices & iPhone OLEDs are capable of proper HDR compositing. I expect the 8 Pro to outperform the S23U in a screen test.
Whilst the S23U screen is great, it's certainly not best in the industry.
