Light Sensor Controllable?

Is there any facility to control the auto light sensor. My past TVs have all had settings to do this. With Toshiba you could even construct your own non-linear curve!

It drops the brightness too low for my room. 
(The Dolby Vision “Dark Room” setting also goes down too far for me)

Seems a bit weird that I can’t customise them?
