Not an expert in lighting, but all I can say is that you have to tonemap it. Lighting in Daz is inaccurate unless tonemapped. I may be able to share some tips:
  1. The default 0.25 burn highlights already overclips the brightness. In some cases, 0.25 works (e.g. plain color background with multiple points of light source, i.e. a studio shot) but if you're shooting indoors/outdoors, never go beyond 0.15. If needed be, reduce crush blacks to lower black clipping.
  2. Fun fact, if you set burn highlights to 0, you're getting almost the equivalence of Blender's AgX/Filmic AgX without the color correction.
  3. Daz's default values for its camera are inaccurate while corresponding to a full-frame (35mm) camera - use IG Photographer's Toolbox: 35mm Cameras instead
  4. Tonemap your scene to get a more accurate GI. Daz default exposure make it as if the light path decays too quickly as it travels. Increase the exposure by tuning shutter speed, f/stop, ISO and/or cm^2 factor and combine with (1). Note that, increasing the exposure does not mean increasing or decreasing the "exposure value" property; you should be making the entire scene brighter by tuning the 4 properties that I've mentioned
Understand how a camera works (particularly full frame), and you'll understand how to roughly tune (4), and also be able to get the DoF you want via the camera properties (mainly the focal length and f/stop).
I'm not very technically savvy, esp with lights and cameras. I'll try to post something soon using your tips.

Nope, setting burn highlights to 0 does not mimic a more accurate result here, it is not properly color corrected for photorealism hence "AgX without the color correction". In any way, Blender's AgX/Filmic AgX is vastly superior.

The sole equivalence here is that both AgX/Filmic AgX and burn highlights=0 is fitting more dynamic ranges into the scene. However, AgX does clip some amount of brightness to retain photorealism, while setting burn highlights to 0 allow virtually unlimited dynamic ranges, which is NOT realistic to the eyes (as well as cameras).

IMO follow your artistic instincts. Depending on lighting conditions, 0.25 may work fine. If it doesn't that means lower the burn highlights to reduce unnatural clipping.

As an example, 0.25 burn highlights with multiple light sources

both pics hurt my eyes ...

During the Prison Riot, Deshawn and Eddie decided to "take care" of Miss Hardmann, the resident psychiatrist.
Alicia later insisted both men had actually protected her throughout the event.
She spoke of their bravery, and selflessness, in standing guard over her office door.

But the prison governer knew the truth, since he'd secretly installed a security camera,
to both spy on the woman he'd known since their college days together, and listen in to her "private" sessions.

Although neither man had sex with Alicia, they'd all got very naked together.
Triggering a profound change in Alicia.
Allowing Governor Hargreaves to blackmail the woman he'd always wanted.

She'd be forced to do things which would not only protect her reputation, but break her marriage vows
to her husband.

Not to worry, Eddie had a younger cousin, CeeCee, who'd "honeypot" Harvey during his dinner break.

Showing Alicia the images of Harvey getting blown in the park would be more than enough
to motivate her!

Alicia's private life was about to change forever.

Time for some kegel exercises, Alicia!

Not sure if it's an improvement, but this is what I tried. Thoughts?
