Is this not 98% of what you want?
To do this, I took this studio HDRI: https://hdrihaven.com/hdri/?c=studio&h=studio_small_05
I increased the brightness of the skybox and got this result with materials:
There is still some residual color from the materials emitting light, but the basic light influx is almost white. The studio lamp appears not to be white, so you may want to look around for a better one. Finally you probably want to use white background, since the studio looks odd. I noticed that increasing the highlight and shadow made the image look better but also more artificial.
As I wrote you in the PM, we are looking into improving our environment (sky, background & sun), I added your use case to the feature request. Maybe we can make this option work out of the box.
