Info:
For anyone using the latest WEG and still facing the black screen issue intermittently, make sure you use the attached the SSDT-PNLF.
The SSDT-PNLF in the hotpatch repo initializes the PWM_FREQ1 to 0xffff which is the root cause of this issue.
Thanks @Fraxul for pointing that out, I would never ever have guessed that.
@RehabMan, I would love to hear you views on this.
Credits: RehabMan for "graphics_PNLF-ACPI100.txt" DSDT patch. The attached SSDT is based on that code.
To conclude, backlight now works 100% of the times. Though I have only tested 15 times, will update in case this issue haunts me ever again.
