It depends on your individual T.V as well. There are differences between OLED and the LCD displays. That is the LCD tech with local dimming arrangements. It's a fine balance between the console settings and your individual displays own HDR adjustments. And of course your own personal viewing tastes as well.
With HDR there is no simple one size fits all solution I am afraid...
HDR has never been all that user friendly. So many different displays etc. I have a JVC 4k projector and it's a totally different animal where HDR is concerned.
Also doesn't the S2 only have 400-450 nits which technically is scaping the bottom of the barrel of what's considered acceptable for HDR?
"The minimum brightness required for a display to be considered "HDR" is generally 400 nits. However, many consider HDR to be more impactful and enjoyable at 600 nits or higher. While a 400-nit display can technically be certified as HDR, the experience may not be as noticeable or impressive compared to displays with higher peak brightness. Content creators often master HDR content with peak brightness levels exceeding 1000 nits, and even 4000 nits."
We all love Nintendo games, but FFS, wait for the OLED model.
