When you open a 32-bit HDR in Photoshop can often see it too dark or too bright, the visual appearance of HDR in Photoshop does not affect the lighting within the scene

A simple way to check the dynamic range, is opening the HDRi with Photoshop, in the bottom left you will find a scroll bar (Exposure bar), the central indicator moves to the left to see underexposure and overexposure to the right of the HDRi.

This exposure bar only works with 32-bit images.

Another way is with the Eyedropper tool, click on the center of the light source and open the Color Picker (Foreground Color) you’ll see the Intensity in steps (real EV) HDR.

I hope this tutorial has been helpful.
