"For example, by convention, all JPEG files are precorrected for a gamma of 2.2."!!!!
:cursing:
In pp, cheked gamma correction =gamma correction of precorrected gamma texture= gamma error

Solution:not to save in jpeg format, using a format  nondestructive and no gamma precorrected ex. png,. tif; hdr, and other
Or, use gamma inverse node in materials room

Sorry for my bad english

Ps:Jpeg=inadapted format for the 3d applications
