Milky colors issue

When I drop a texture  to Painter its ok  .    But when I drop sbsar having  color image input  or just color input it's always milky colors.       Like if  Painter does extra   gamma correction ignoring  the input is sRGB .  

  I recall there were  small button before   next to each input  where  you could set  if it's srgb or non-color  or something like that.    It was simple  and easy like in Blender. 

Now I couldn't understand a thing.

Could somebody explain  it please .   What current  rules are ?     I use default legacy color managment since I work for games.
