Batch-Generate Previews > Object = Low Lightning

[mond-cz]

Current Object Previews (Thumbnails) are generated with very subtle light condition even on default Cube very hard to see something. Is it possible to increase strength or light type used for this purpose, to make this feature more useful?

Am I right?
2.79 Scene / 2.82 Collection both use Cycles scene lights
For 2.79 Object are used studio lights (GLSL)
For 8.82 Object is used Cycles with temporarily generated Point light?

Thank you for help and sorry if I'm on a totally wrong place to ask.
